Question

Why must electrostatic field at the surface of charge boafy is always proportional

Answer 1

Answer:

The charges on the surface of a conductor are static, that is, they do not experience any force. It is only when there is no component of electric field along the surface of charged body.

Hence electric field is normal to the surface.

Answer 2

Answer:

mark me as brainliest and support me to give more valuble answers

Explanation:

So that tangent on charged conductor gives the direction of the electric field at that point.
