Question
A charge is placed at a point. As the distance of observation from the charge increases, the potential energy across the charge
- Remain constant
- Increases
- Decreases
- Cannot be determined
Hint:
U=Kq1q2/r (where K= 1/4πε, q= charges, r= distance between the two charges)
The correct answer is: Decreases
- Potential energy is inversely proportional to the distance between the two charges.
- Therefore, as the distance increases, the potential energy decreases.
- So, the correct option is c.
