Why ust electrostatic field be noral to the surface at every point of a carged conductor.

Why should electrostatic field be zero inside.

Answer the following questions: Magnetic field lines are always nearly normal to the surface of a ferromagnet at every point. (This fact is analogous to the static electric field lines being normal to the surface of a conductor at every point.) Why?

Answer carefully: We know that electric field is discontinuous across the surface of a charged conductor. Is electric potential also discontinuous there?

The electrostatic potential on the surface of a charged conducting sphere is 100 V. Two statements are made in this regard: S_1 : At any point inside the sphere, electric intensity is zero. S_2 : At any point inside the sphere, the electrostatic potential is 100 V. Which of the following is a correct statement?

Show that the electric field at the surface of a charged conductor is given bu vecE = sigma/epsilon_0 hatn , where sigma is the surface charge density and hatn is a unit vector normal to the surface in the outward direction.

Why do the electrostatic field lines not form closed loops?

Why electric intensity at any point inside a charged conductor is zero?

Show that the tangential component of electrostatic field is continuous from one side of a charged surface to another.
