Which of the following statements is not correct?

Correct option is A

The correct answer is (A) Gravitational force is strongest in small bodies.

Explanation:
• Newton's Universal Law of Gravitation states that the gravitational force between two bodies is directly proportional to the product of their masses (F ∝ m1 × m2).
• Because of this direct proportionality, massive bodies (like stars, planets, and moons) possess enormously strong gravitational forces, while small bodies (like humans, apples, or dust) have infinitesimally weak gravitational forces.
• Therefore, the statement claiming gravitational force is strongest in "small bodies" is factually incorrect.

Information Booster:
• Universal Law Equation: The complete formula is F = G × (m1 × m2) / r², where 'r' is the distance between their centers.
• Weakest Fundamental Force: Of the four fundamental forces of nature (gravity, electromagnetism, strong nuclear, weak nuclear), gravity is by far the weakest, yet it shapes the cosmos because it has an infinite range and is always cumulative (attractive).

Additional Knowledge:
• Option B (Value of G): The universal gravitational constant (G = 6.674 × 10^-11 N m²/kg²) is considered exactly the same everywhere in the observable universe.
• Option C (Every object attracts): This is the foundational premise of universal gravitation. The pen on your desk is gravitationally attracting you right now, though the force is negligible.
• Option D (Always attractive): Unlike electromagnetism, which can attract or repel based on charges, gravity only ever pulls matter together.
