A charge Q is given to a conducting cone. Is charge density on the cone it all the points is same?

A charge Q is given to a conducting cone. Is electric potential at all the points on the surface of the cone same?

Define volume charge density ?

A point charge +q , is placed at a distance d from an isolated conducting plane. The field at a point P on the other side of the plane is

Two identical point charges of charge Q are kept at a distance r from each other. A third point charge is placed on the line joining the above two charges, such that all the three charges are in equilibrium. Calculate the magnitude and location of the thrid charge.

What would be the work done if a point charge + q is taken from a point A to the point on the circumference of a circle with another point charge +q at the centre?

A spherical conducting shell of inner radius r_1 and outer radius r_2 has a charge Q as shown in the figure. A charge q is placed at the centre of the shell. What is the surface charge density of the inner and outer sufaces of the shell?

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…………….. .

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 .
