What is the force of attraction between objects due to their masses?

• A. Gravity
• B. Contact Force
• C. Field Force
• D. Displacement

Answer: (A)

The force in play is the gravitational pull that two masses exert on each other. Gravity is the attraction that acts even when objects aren’t touching, and it depends on how big the masses are and how far apart they are. The precise description is given by Newton’s law of universal gravitation, which shows the force grows with the product of the masses and shrinks with the square of the distance between them. This makes gravity the best answer because it specifically names the force responsible for mass-based attraction. It’s not a contact force (that would require objects to touch, like friction or a normal force), and displacement is a description of motion, not a force. Field force is a broader category that includes gravity, but naming gravity identifies the exact force involved.
