A conducting shell `S_1` having a charge Q is surrounded by an uncharged concentric conducting spherical shell `S_2`. Let the potential difference between `S_1` and that `S_2` be V. If the shell `S_2` is now given a charge `-3Q`, the new potential difference between the same two shells is

A

`V`

B

`2V`

C

`4V`

D

`-2V`

Text Solution

Verified by Experts

The correct Answer is:
A
According to principle of generator `PD` in this case only depends on the charge on inner shell.

A solid conducting sphere having a charge Q is surrounded by an uncharged concentric conducting hollow spherical shell. Let the potential difference between the surface of the solid sphere and that of the outer surface of the hollow shell be V. If the shell is now given a charge of -3Q , the new potential difference between the same two surfaces is :

A solid conducting sphere, having a charge Q, is surrounded by an uncharged conducting hollow spherical shell. Let the potential difference between the surface of the solid sphere and that of the outer surface of the hollow shell be V. If the shell is now given a charge of -4 Q, the new potential difference between the same two surfaces

A conducting sphere is enclosed by a hollow conducting shell. Initially the inner sphere has a charge Q while the outer one is uncharged. The potential difference between the two spherical surface is found to be V. later on the outer shell is given a charge -4Q. The new potential difference between the two surfaces is : (A) V (B) -V (C) -2V (D) 2V

There are two concentric conducting spherical shells of radius r_A and r_B respectively (r_B= 2r_A) . If the inner shell is given a charge Q and outer shell is given a charge 2Q, then the potential difference between the surfaces of the shells will be K=1/(4piepsilon_0)

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

A solid conducting sphere of radius a is enclosed in a concentric shell of radius b gt a . The charge on the inner sphere is 3muC and on the conducting shell is -10muC . The potential difference between the conductors is V. If +10muC additional charge is given to the outer shell, the new potential difference is

Assertion: Two concentric charged spherical shells are given. The potential difference between the shells depends on charge of inner shell. Reason: Potential due to charge of outer shell remains same at every point inside the sphere.
