Question

electric field intensity inside the conductor is always zero , why???​

Answer 1

Explanation:

In electrostatics free charges in a good conductor reside only on the surface.

There are at least two ways to understand this:

The free charge inside the conductor is zero. So the field in it is caused by charges on the surface. Since charges are of the same nature and distribution is UNIFORM, the electric fields cancel each other.

Consider a Gaussian surface inside the conductor. Charge enclosed by it is zero (charge resides only on surface). Therefore electric flux =0 Furthermore, electric flux = electric field * area. Since area cannot be zero, electric field is zero

Answer 2

Because inside the condutor there is no net charge.. If any charge is present the it reside to the surface... Thus there is no charge inside thus a/c to gauss law there is no electric field.
