Figure shows three concentric thin spherical shells A, B and C of radii a, b and c respectively. The shells A and C are given charges q and -q respectively and the shell B is earthed. Find the charges appearing on the surfaces of B and C.

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,

Figure shows three concentric thin conducting spherical shells A, B and C of radii R, 2R and 3R. The shell B is earthed A and C are given charges q and 2q respectively. Find the charges appearing on all the surface of A,B and C. [inner surface (A)0,(B)-q,(C) 4/3 q Outer surface (A) q, (B)-4/3 q,(C) 2/3 q]

Figure shows three concentric thin spherical shells A, B and C. They have radii R, 2R and 3R. The shell B is earthed and A and C are given charges q and 2q respectively. Then, the total charge on B is

Four concentric conducting spherical shells A, B, C and D of radii a, 2a, 3a and 4a respectively. Shell B and D are given charges q and -q respectively. If shell C is grounded then potential difference (VA — VC) is

There are four concentric shells A, B, C and D of radii a, 2a, 3a and 4a respectively. Shells B and D are given charges +q and -q respectively. Shell C is now earthed. The potential difference V_A-V_C is

Figure shows a system of three concentric metal shells, A, B and C with radii a, 2a and 3a respectively. Shell B is earthed and shell C is given a charge Q. Now if shell C is connected to shell A, then find the final charge on the shell B
