Question
Two positive charges are equal. Which has less electric potential energy?
- Charge A
- Charge B
- None of them
- Both of them
Hint:
For, unlike charges potential energy decreases.
The correct answer is: Charge B
- Electric field lines are from higher potential(positive charge) to lower potential(negative charge).
- Charge B is positive and is at a lower potential(towards negative charge), condition of unlike charges.
- Charge A is positive and is at a higher potential(towards positive charge), condition of like charges.
- For, unlike charges potential energy decreases.
- So, the correct option is b.
