Answer 1

Answer:

Electric Field is non zero but Electric potential is zero.

Explanation:

Four Charges Placed at Corners and Each Having distance R from the centre of the Square.

Potential(V)=KQ/R

V=K(2)/R-K(3)/R-K(4)/R+K(5)/R

By solving

We get V=0

Electric field directions are not canceling each other hence Electric field will be non zero.

Take Centre point P has positive you will get the directions.
