Question
What can you say about the work done when a +1 C charge is moved from -3V to +3V?
- Work is done on the charge
- Work is done by the charge
- Incomplete information
- Work done is zero
Hint:
Work is done on the charge.
The correct answer is: Work is done on the charge
- Positive charges move in the direction of the electric field, from the higher potential to the lower potential.
- Therefore, work is done on the charge to move it from the negative potential to the positive potential.
- So, the correct option is a.
