What effect does changing mass have on the acceleration of an object

Increasing force tends to increase acceleration while increasing mass tends to decrease acceleration. Thus, the greater force on more massive objects is offset by the inverse influence of greater mass. Subsequently, all objects free fall at the same rate of acceleration, regardless of their mass.

Option (b) is the correct answer.

Explanation:

Potential energy is the energy obtained by an object due to its position. Whereas kinetic energy is the energy obtained by an object due to its motion.

For example, when a charge moves from one point to another then it means the charge has come to motion.

Thus, we can conclude that potential energy of a stationary charge when it begins to move freely from one point to another under the influence of an electric field decreases.
