    If it will not be normal then a component of the electric line or you can say electric field will come along the surface . Suppose ECostheta now as we know that potential difference = integral of Ecostheta. dr thus there will be a potential difference but a conductor is always equipotential and thus it will have 0 potential difference so our assumption of not taking electric field line Perpendicular to the surface of conductor was wrong this Principle is called Total normal electrostatic induction(TNEI)
