358046 A charged conductor produces an electric field of intensity \({10^3}V/m\) just outside its surface in vacuum. Then, it produces the electric field of intensity \(E\) just outside its surface, when it is placed in a medium of dielectric constant 4. The value of \(E\) will be

358047 Assertion :
Electric field inside conductor is zero.
Reason :
If a conductor is given charge then no excess inner charge appears.
