Two concentric spherical metal shells have radii R and 2R, respectively.The inner shell has charge Q,and the outer shell has charge -2Q.Potential at the centre of the combination is `V_(1)`.Now the outer shell is grounded and potential at the centre becomes `V_(2)`.Find the value of `V_(2)`-`V_(1)`

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 spherical metal shells of radii r_(1) and r_(2) (r_(2) gt r_(1)) . If the outer shell has a charge q and the inner one is grounded, then the charge on the inner shell is

In (Fig. 3.73), if the inner shell has charge +q_0 and the outer shell is earthed, then . i. determine the charge on the outer shell, and ii. find the potential of the inner shell.

If the electric potential of the inner shell is 10 V and that of the outer shel is 5V , then the potential at the centre will be

Two concentric spheres of radii R and 2R are charged. The inner sphere has a charge if 1muC and the outer sphere has a charge of 2muC of the same sigh. The potential is 9000 V at a distance 3R from the common centre. The value of R is

Consider two concentric spherical metal shells of radii 'a' and bgt a .The outer shell has charge Q but the inner shell has no charge.Now the inner shell is grounded ,This means that the inner shell will come at zero potential and that electric fields lines leave the outer shell and end on the inner shell.(a) Find the charge on the inner shell Find the potential on outer sphere.

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 concentric conducting sphereical shells carry charges +4Q on the inner shell -2Q on the middle shel and +6Q on the outer shell. The charge on the inner surface of the outer shell is

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

Two concentric spherical conducting shells of radii R and 2R are carrying charges q and 2q, respectively. Both are now connected by a conducting wire. Find the change in electric potential (inV) on the outer shell.
