Problems on concentric shells

In the given figure there are two concentric shells find potential difference between spheres.

The potential on the Nth shell due to N concentric shells having charges Q , 2Q , 3Q ,…… NQ and radii a , 2a , 3a ….. Na respectively is

Problems related to concentric circles

There are two concentric spherical shell of radii r and 2r . Initially, a charge Q is given to the inner shell and both the switches are open. The twio steps of the above two problems are repeated b times, the potential differences between the shells will be

There are two concentric metallic shells of radii R and 2R, if outer shell is given charge q_1 , then charge on surface of inner shell will be

There are two concentric spherical shell of radii r and 2r . Initially, a charge Q is given to the inner shell and both the switches are open. If switch S_1 is closed and then opened, charge on the outer shell will be

Three conducting concentric shell s A,B, and C of radius a,2a,3a are as shown in the figure.The charge on shell B is Q ..The switch S is closed.Then after closing the switch The charge on outermost shell is

Three conducting concentric shell s A,B, and C of radius a,2a,3a are as shown in the figure.The charge on shell B is Q ..The switch S is closed.Then after closing the switch The charge on innermost shell is
