A uniform electric field `vecE` directed vertically upwards exists in a region of space. A point mass m carrying positive charge q is a state of equilibrium inside this electric field

A

The point mass in in stable equilibrium

B

The point mass in in unstable equilibrium

C

The point mass is in a state of neutral equilibrium

D

Equilibrium is not possible

Text Solution

Verified by Experts

The correct Answer is:
C
Inside a uniform electric field the net force will remain zero everywhere. Such type of equilibrium is called neutral equilibrium.
