Two concentric metallic spherical shells are given positive charges . Then

Two conducting concentric spherical shells are given positive charges. Choose the correct outcome.

Two concentric metallic spherical shell of radii R and 2R are given charges Q_(1) & Q_(2) respectively. The surface charge density on the outer surfaces of the shells are equal. Determine the ratio Q_(1)=Q_(2)

There are two concentric spherical shells with inner shell having positive charge q and outer shell having a charge -q. Now outer shell is supplied a charge -2q and inner shell is earthed, Calculate the ratio of initial and final capacities of the system. (If a = 3R, b= 5R)

Three concentric metallic spherical shells of radii R, 2R, 3R are given charges Q_(1) Q_(2) Q_(3) , respectively. It is found that the surface charge densities on the outer surface of the shells are equal. Then, the ratio of the charges given to the shells Q_(1) : Q_(2) : Q_(3) is

Figure shows three concentric metallic spherical shells. The outermost shell has charge q_(2) , the inner most shell has charge q_(1) , and the middle shell is uncharged. The charge appearing on the inner surface of outermost shell 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.
