What is the force of attraction between any two bodies by virtue of their masses is called?
Correct answer: B. Gravitational Force
- A. Electromagnetic Force
- B. Gravitational Force
- C. Centripetal Force
- D. Nuclear Force
Explanation
The mutual force produced by the masses of two bodies is gravitational force, described by Newton's law of gravitation. It acts between all masses and is distinct from centripetal force, which is the name for the inward net force required in circular motion. Students may choose centripetal force by confusing an effect of circular motion with the cause of attraction between masses.

About Newton's Laws of Motion
Newton’s laws explain inertia, the relation between net force and acceleration, and action-reaction pairs. Questions involve free-body diagrams, balanced and unbalanced forces, F = ma, force as the rate of change of momentum, and identifying genuine third-law pairs, which act on different bodies.
