Question

The electric field and the electric potential at a point inside a shell are E and V respectively. Which of the following is correct?

• A. If $E=0$, V must be zero.
• B. If $V=0$, E must be zero.
• C. If $E\ne 0$, V cannot be zero.
• D. None of these

Answer 1

The correct option is D None of these

In a shell $E=0$ but $V\ne 0$.
Along the equatorial line of a dipole, $V=0$ but $E\ne 0$.
