Show that charge always resides on the outer surface of a conductor.

The question given below consist of an assertion (A) and a reason ( R). Use the following key to choose the appropriate answer to these questions from the codes (a), (b), ( c) and (d) given below: Both A and R are true and R is the correct explanation of A. Both A and R are true but R is NOT the correct explanation of A. A is true but R is false. A is false and R is also false. Assertion: Charge always resides on the outer surface of a conductor. Reason:The net charge in the interior of a conductor is zero.

A conductor A with cavity as shown in the figure a charge Q. Show that the entire charge must appear on the outer surface of the conductor.

A conductor A with a cavity as shown in Fig. 1.36(a) is given a charge Q. Show that the entire charge must appear on the outer surface of the conductor.:

A point charge +Q is placed at the centre O of an uncharged hollow spherical conductor of inner radius 'a' and outer radius 'b'. Find the following: The magnitude and sign of the charge induced on the inner and outer surface of the conducting shell.

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.

A conductor A with a cavity as shown in Fig. is given a charge Q.. Another conductor B with charge q is inserted into the cavity keeping B insulated from A. Show that the total charge on the outside surface of A is Q + q .

Fill ups A point charge is placed at the centre of a hollow conducting sphere of internal radius 'r' and outer radius '2r'. The ratio of the surface charge density of the inner surface to that the outer surface will be…………….. .

Show that the potential is constant within and at the surface of a charged conductor.

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?
