Answer:
Explanation:
as electric potential is a scalar quantity so it can never be zero
only if we put test charge at infinity so no influence of the charge is observed we can say that the potential at infinity is zero
If we consider electric field so it is zero at
right of -4muc at a distance [2/(root5 -2 )]m
