Two conducting sphere of radii a and b are placed at separation d. It is given that d gt gt a and d gt gt b so that charge distribution on both the sphere remains spherically symmetric. Assume that a charge + q is given to the sphere of radius a and -q is given to the sphere of radius b. (i) Write the electrostatic energy (U) of the system and calculate the capacitance of the system using the expression of U. (ii) Prove that the capacitance of the system is given by (1)/(C)=((1)/(4 pi in_(0)a)+(1)/(4 pi in_(0)b))"if" d rarr infty

A metallic sphere of radius R has a small bulge of hemispherical shape on its surface. The radius of the bulge is r. If a charge Q is given to the sphere, calculate the quantity of charge on the surface of the bulge. Assume that charge is uniformly distributed on the surface of the bulge (though it is wrong !) and also on the remaining surface of the sphere.

    Paragraph for Questions 53 and 54: An isolated system consists of two conducting spheres A and B. Sphere A has five times the radius of sphere B. Initially, the spheres are given equal amounts of positive charge and are isolated from each other. The two spheres are then connected by a conducting wire. Note: The potential of a sphere of radius R that carries a charge Q is V = kQ//R , if the potential at infinity is zero. Determine the ratio of the charge on sphere A to that on sphere B, q_A // q_B , after the spheres are connected by the wire.

    A conducting sphere of radius R and carrying a charge Q is joined to an uncharged conducting sphere of radius 2R . The charge flowing between them will be
