In the figure two concentric conducting shells of radius R & 2R are shown. The inner shell is charged with Q and the shell is unchanged. The amount of energy dissipated when the shells are connected by a conducting wire is:

Consider two concentric metalic shell's of radii R and 2R. The inner shell is having charge Q and outer shell is uncharged. If they are connected with a conducting wire. Then,

Consider two concentric metalic shell's of radii R and 2R. The inner shell is having charge Q and outer shell is uncharged. If they are connected with a conducting wire. Then,

Two concentric conducting shells of radii R and 2R are having charges Q and -2Q respectively.In a region r

Two concentric thin conducting sphereical shells having radii R and 2R are as shown in the figure .A charge +Q is given to the shell A and -4Q is given to the shell B .If A and B are connected by a thin conducting wire then the amount of heat produced after the connection is

Two thin conducting shells of radii R and 3R are as shown in the fig. External shell carries a charge +Q and inner shell neutral. The inner shell is earthed with the help of a switch S . Then

Two thin conducting shells of radii R and 3R are as shown in the fig. External shell carries a charge +Q and inner shell neutral. The inner shell is earthed with the help of a switch S . Then

Figure shows two conducting thin concentric shells of radii r and 3 r . The outer shell carries charge q and the inner shell is neutral . The amount of charge that flows from the inner shell to the earth after the key K is closed is equal to (1//n)^(th) of the charge on the outer shell. What is the value of n ? .

Two thin conducting shells of radii R and R ar shown in figure . The outer shell carries a charge +Q and the inner shell is neutral. The inner shell is earthed with the help of switch S . Find the charge attained by the inner shell. .
