Concepts Of Physics MCQ Edition [Volume 2]PhysicsElectric Field and Potential
When a positive charge is moved from a region of lower potential to a region of higher potential, its electric potential energy
Options
- Adecreases
- Bmay increase or decrease
- Cremains the same
- Dincreases
Correct answer
D. increases
Step-by-step solution
The electric potential energy U of a charge q at a point with electric potential V is given by U = qV . When the charge is moved from a region of lower potential V₁ to a region of higher potential V₂ , the change in potential is V = V₂ - V₁ > 0 . The change in electric potential energy is U = q V . Since the charge is positive ( q > 0 ) and the change in potential is positive ( V > 0 ), the change in potential energy U is positive. Therefore, the electric potential energy of the positive charge increases.
