A spherical metal shell A of radius `R_A` and a solid metal sphere B of radius `R_B(ltR_A)` are kept far apart and each is given charge `'+Q'`. Now they are connected by a thin metal wire. Then

Two spherical conductors A and B of radii R and 2R respectively are each given a charge Q. When they are connected by a metallic wire. The charge will

A spherical conductor A of radius r is placed concentrically inside a conducting shell B of radius R(R gt r) . A charge Q is given to A , and then A is joined to B by a metal wire. The charge flowing from A to B will be

A spherical conductor A of radius r is placed concentrically inside a conducting shell B of radius R(R gt r) . A charge Q is given to A , and then A is joined to B by a metal wire. The charge flowing from A to B will be

Figure shows a solid metal sphere of radius a surrounded by a concentric thin metal shell of radius 2a. Initially both are having charges Q each, When the two are connected by a conducting wire as shown in the figure, then amount of heat produced in this process will be :
