MCQ

If A and B are two equipotential surfaces around a positive point charge q, what will happen if we place another point charge +Q between A and B?

A
It will remain stationary
B
It will move from B to A
C
It will move from A to B
D
It will rotate in a circular path

✓

Answer

It will move from A to B

Explanation:

A charge always tries to move from a point of higher potential to a point of lower potential. The potential at A is greater than the potential at B because of electric potential decreases with distance from the charge. It can also be explained by the fact that a positive charge is always repelled by another positive charge.
