NEET Physics MCQs for Gravitation Chapter

The Gravitation chapter in Physics is a fundamental part of the NEET syllabus. It introduces students to the concepts of gravitational force, laws of motion, and planetary motion, all of which are crucial for understanding various phenomena in nature. Mastery of this chapter is essential for aspiring medical students, as it not only forms the basis of many questions in the NEET exam but also builds the foundation for other chapters in Physics.

In this article, we will dive into some of the most important Multiple Choice Questions (MCQs) from the Gravitation chapter. This guide will help you not only prepare effectively for the exam but also strengthen your understanding of the topic.

Key Concepts in Gravitation

The Gravitation chapter in the NEET Physics section is one of the most important chapter that students need to study in process to complete their preparations. NEET Physics Gravitation chapter MCQs focus on understanding the universal law of gravitation, Kepler’s laws, acceleration due to gravity and its variation, gravitational potential energy, and the dynamics of satellites, including escape velocity, orbital velocity, and geostationary satellites. Before diving into the MCQs, let’s quickly revisit the important concepts in the Gravitation chapter:

  • Newton’s Law of Gravitation:
    This law states that every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
  • Gravitational Constant (G):
    The gravitational constant is a universal constant that appears in the law of gravitation. Its value is approximately

    6.67×1011N m2/kg26.67 \times 10^{-11} \, \text{N m}^2/\text{kg}^2

    .

  • Gravitational Potential Energy:
    The potential energy due to gravitational force is the energy an object possesses because of its position in a gravitational field. It is given by the formula

    U=GMmrU = – \frac{GMm}{r}

    , where

    GG

    is the gravitational constant,

    MM

    and

    mm

    are the masses of two bodies, and

    rr

    is the distance between them.

  • Escape Velocity:
    The escape velocity is the minimum velocity needed by an object to break free from the gravitational pull of the Earth (or any celestial body). It can be calculated using the formula

    ve=2GMrv_e = \sqrt{\frac{2GM}{r}}

    .

  • Orbital Motion and Kepler’s Laws:
    Kepler’s Laws describe the motion of planets in their orbits. These laws are crucial to understanding the relationship between the masses of celestial bodies and their gravitational forces.

NEET Physics MCQs on Gravitation

Ahead, we have added some of the NEET Physics MCQs from Gravitation Chapter so that all the students appearing for the exam can check and complete their preparations for the same using them. Scroll down in the article below to check the NEET Physics MCQs on Gravitation:

Question 1: What is the value of the gravitational constant

GG

?

a)

6.67×1011N m2/kg26.67 \times 10^{-11} \, \text{N m}^2/\text{kg}^2


b)

9.8N/kg9.8 \, \text{N/kg}


c)

1.6×1019N m2/kg21.6 \times 10^{-19} \, \text{N m}^2/\text{kg}^2


d)

9.8m/s29.8 \, \text{m/s}^2

Answer: a)

6.67×1011N m2/kg26.67 \times 10^{-11} \, \text{N m}^2/\text{kg}^2

Explanation: The gravitational constant is a fundamental constant of nature and has a fixed value of

6.67×1011N m2/kg26.67 \times 10^{-11} \, \text{N m}^2/\text{kg}^2

, which is crucial for calculating gravitational forces between two masses.

Question 2: The escape velocity from the surface of Earth is approximately:

a)

11.2km/s11.2 \, \text{km/s}


b)

9.8m/s29.8 \, \text{m/s}^2


c)

5.0km/s5.0 \, \text{km/s}


d)

1.6km/s1.6 \, \text{km/s}

Answer: a)

11.2km/s11.2 \, \text{km/s}

Explanation: The escape velocity from the Earth’s surface is calculated using the formula

ve=2GMrv_e = \sqrt{\frac{2GM}{r}}

. The value is approximately

11.2km/s11.2 \, \text{km/s}

, which is the minimum speed an object must have to escape the Earth’s gravitational pull without further propulsion.

Question 3: The force of attraction between two masses is 50 N when the distance between them is 1 meter. What will be the force when the distance is reduced to 0.5 meters?

a) 100 N
b) 200 N
c) 25 N
d) 50 N

Answer: b) 200 N

Explanation: According to Newton’s Law of Gravitation, the force is inversely proportional to the square of the distance between the two masses. If the distance is reduced to half, the force will increase by a factor of 4 (since

F1r2F \propto \frac{1}{r^2}

). Therefore, the new force is

50×4=200N50 \times 4 = 200 \, \text{N}

.

Question 4: Which of the following statements is true about the gravitational potential energy of two masses

MM

and

mm

?

a) The gravitational potential energy is positive for all pairs of masses.
b) The gravitational potential energy is negative for all pairs of masses.
c) The gravitational potential energy is always zero.
d) The gravitational potential energy can be positive or negative depending on the position of the masses.

Answer: b) The gravitational potential energy is negative for all pairs of masses.

Explanation: The gravitational potential energy between two masses is always negative, as it is defined as

U=GMmrU = – \frac{GMm}{r}

, where

rr

is the distance between the masses. The negative sign indicates that the gravitational force is attractive and the system of masses is bound together.

Question 5: Which of the following is not a consequence of Kepler’s third law of planetary motion?

a) The square of the period of revolution of a planet is directly proportional to the cube of the semi-major axis of its orbit.
b) The orbital period of a planet increases as the distance from the sun increases.
c) All planets move in elliptical orbits with the sun at one focus.
d) The planets sweep equal areas in equal times.

Answer: c) All planets move in elliptical orbits with the sun at one focus.

Explanation: This statement refers to Kepler’s first law, not the third law. Kepler’s third law relates to the relationship between the orbital period and the size of the orbit.

Question 6. What happens to the gravitational potential at the centre of the uniform spherical shell which shrinks gradually?

  • Remains constant
  • Decreases
  • Increases
  • Oscillates

Answer: (b) Decreases

Question 7. Choose the factor on which the orbital velocity does not depend when the satellite is orbiting close to the earth’s surface

  • The mass of the earth
  • The mass of the satellite
  • The orbital radius
  • The radius of the earth

Answer: (b) The mass of the satellite

Question 8. The atmosphere around the earth is held by

  • Gravity
  • Winds
  • Clouds
  • None of the above

Answer: (a) Gravity
