Among the following, the weakest force is:

Correct option is B

The correct answer is (b)  Gravitational force

Explanation:

The gravitational force is the weakest among the listed forces. It is the force of attraction between masses and operates over large distances, but its strength is much weaker compared to the other fundamental forces.

• Electric force is stronger than gravitational force and acts between charged particles. It is much stronger than gravity, especially over short distances.
• Buoyant force acts on objects submerged in a fluid, equal to the weight of the displaced fluid, but it is not a fundamental force and is stronger than gravity in certain contexts (such as floating objects).
• Nuclear force is the strongest force, acting at the subatomic level between particles in the nucleus of an atom, like protons and neutrons.

Information Booster:

• The gravitational force is always attractive, acts on masses, and is the weakest fundamental force. Its strength diminishes with the square of the distance between the masses.
• Fundamental forces in order of strength:

1.       Nuclear Force (Strongest)

2.       Electromagnetic Force

3.       Weak Nuclear Force

4.       Gravitational Force (Weakest)
