A spherical capac

Answer :

Radius of the outer shell = r₁

Radius of the inner shell = r₂

Charge on the inner surface of the outer shell = Q

Charge on the outer surface of the inner shell = -Q

Potential difference between the two shells,

Where, = Absolute Permittivity of free space = 8.8510^-12C²N^-1m^-2

Since, Capacitance,

Hence, proved.
