Two metal spheres, one of radius R and the other of radius 2R, both have the same surface charge density s. They are brought in contact and separated. What will be new surface charge densities on them?

Two identical plane metallic surfaces A and B are parallel to each other in air separated by a distance of 1 cm as shown in the fig. Surface A is given a postive potential 10 V and the outer surface of B is earthend What is the magnitude and direction of the uniform electric field between points Y and Z?

Two parallel metal plates having charge +Q and -Q face each other at a certain distance between them. If the plates are now dipped in kerosene oil tank, the uniform electric field between the plates will

Show that the force on each plate of a parallel plate capacitor has a magnitude equal to (1/2) QE, where Q is the charge on the capacitor, and E is the magnitude of electric field between the plates. Explain the origin of the factor 1/2.

Show that the plates of a parallel plate capacitor attract each other with a force given by F = Q^2/(2epsilon_0A) The symbols have their usual meanings?
