Question

Why the field lines due to a point charge near a conductor are normal to the conductor at every point?

Answer 1

Answer:

it necessary that the field lines from a point charge placed in the vicinity of a conductor must be normal to the conductor at every point. would have a tangential component which will make electrons move along the surface creating surface currents and the conductor will not be in equilibrium.
