A cube has point charges of magnitude - q at all its vertices. Electric field at the center of the cube is:
A
B
C
zero
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Clearly, the electric-field of each point charge is equal and opposite to the electric-field of charge diagonally opposite to it. So, the net electric field at centre of the cube is zero.
