If a test charge is moved from a lower potential area to a higher potential area, then theelectric potential energy
Correct answer: A. Increases.
- A. Increases.
- B. Decreases.
- C. Becomes zero.
- D. Remains the same.
Explanation
Electric potential energy is the energy a charge has due to its position in an electric field. When a positive test charge is moved against the electric field from a region of lower potential to a region of higher potential, work is done on the charge, and thus its electric potential energy increases. This is analogous to lifting an object in a gravitational field, where lifting to a higher height increases gravitational potential energy.Choice A is correct because moving to a higher potential increases energy. Choice B is incorrect because energy would decrease only if moving to a lower potential. Choice C is incorrect because potential energy is not zero unless specifically defined at a point. Choice D is incorrect because a change in potential implies a change in potential energy.

About Electric Potential
Electric potential is the work done per unit positive charge in bringing it from infinity to a point, while potential difference compares energy change between two points. Work includes potential due to point charges, superposition of scalar potentials, equipotential surfaces, and the relation between electric field and potential.
