Answer 1

heya...!!!

✔here is ua answer:

_________________________________________❤

If a charge is set into motion, then theconductor is not in a state ofelectrostatic equilibrium. Therefore, the electric field must be entirelyperpendicular to the conductingsurface for objects that are atelectrostatic equilibrium. ... As,electric field inside the conductor is always zero.

hope it helps...!!!❤

Answer 2

Explanation:

${\mathfrak{\red{\huge{Hola\:mate}}}}$

Electric field is defined to be the gradient of potential and the surface of a conductor has a constant potential. Therefore, there is no field along the surface of the conductor and, hence, the electrostatic field at the surface of a charged conductor should be normal to the surface at every point..
