Why the electric field at the outer surface of a hollow charged conductor is normal to the surface?

Text Solution

Verified by Experts

The electrostatic field be normal to the surface at every point of a charge conductor. Electric field inside the conductor is always zero. The electric lines of force exert lateral pressure on each other leads to explain repulsion between like charges.
