Assertion: The surface charge densities of two spherical conductors of different radii are equal. Then the electric field intensities near their surface are also equal. Reason: Surface charge density is equal to charge per unit area.

The capacity of a spherical conductor is

A number of spherical conductors of different radii have same potential. Then the surface charge density on them.

Assertion (A): If two spherical conductors of different radii have the same surface charge densities, then their electric field intensities will be equal. Reason (R ): Surface charge density =("Total charge")/("area")

A number of spherical conductors of different radii are charged to same potential. The surface charge density of each conductor is related with its radius as

A number of spherical conductors of different radii are given charge such a that the charge density of each condutor is inversely proportional to its radius. The conductors will have

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

The surface charge density of an irregularr shaped conductor is
