Question

Prove that the electric field inside a conductor is zero and is perpendicular to the surface of conductor at every point.

Answer 1

Answer:

Explanation:

As we know, the electric lines of force represent the direction of electric field at that point.

Imagine a point charge placed in a region. Then as we know, the concentric Spherical surfaces are equipotential surfaces. If the line is not perpendicular to the plane. Then there must be a component of force parallel to the surface. Then if you are moving a charge particle on the spherical surface, then the amount of work is,

W=F∥x≠0∴∆V=Wq=F∥xq≠0

So, since the potential difference is not zero. The surface is going to be perpendicular to the surface.
