Question

The electric field inside an electrically charged conductor is :

• A. very high
• B. zero
• C. negative
• D. can be any random value

Answer 1

The correct option is B zero

The electric field intensity at a point is given by the formula $E=\frac{q}{4\pi {ϵ}_{0}k{r}^2}$. where $q$ is the charge producing the field,

${ϵ}_0$ is the permittivity of free space, $k$ is the dielectric constant of the medium and $r$ is the distance between the point of the electric field and the charge. For conductors, $k$ is infinite. Hence no field is present in it.
