At any point inside the conductor electric field remains zero.

Q. A hollow metallic surface of radius $10 c m$ is given a charge of $3.2 \times 1 0^{- 19}$ coulomb. The electric potential at a point $4 c m$ from the centre is

$9 \times 1 0^{- 9} N C^{- 1}$

$288 N C^{- 1}$

$2.88 N C^{- 1}$

zero

At any point inside the conductor electric field remains zero.
