A charge 2Q is distributed over three concentric non-conducting spherical shells of radii a, b, c (a < b < c) such that their surface charge densities are equal to one another. The total potential at a point at distance r from their common centre, where r < a , would be:

A charge q is distributed over two concentric hollow sphere of radii a and b(bgtc) such that the surface densities are equal.Find the potential at the common centre.is

Consider an assembly of three conducting concentric spherical shells of radii a,b and c as shown in figure. Find the capacitance of the assembly between the points A and B.

Figure shows three concentric conducting spherical shells of radii a,b and c (c gt b gt a) . The innermost and outermost shell are given charge s Q_(1) and Q_(2) respectively, and the middle shell had been earthed. Select the correct alternative(s) .

Figure shows three concentric thin spherical shells A, B and C of radii a, b, and c. The shells A and C are given charge q and -q, respectively, and shell B is earthed. Then,

Charges Q, 2Q , and -Q are given to three concentric conducting sphereical shells A, B and C respectively as shown in figure. The ratio of charge on the inner and outer surface of shell C will be
