Question

What happens to the potential energy of a stationary charge when it begins to move freely from one point to another under the influence of an electric field?
It increases.
It decreases.
It remains the same.
It becomes zero.

Answer 1

It decreases and the decrease in the energy level appear as a kinetic energy of the charge

Answer 2

Answer: 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.
