The capacitance of two concentric spherical shells of radii R1andR2(R2>R1) is:
The radii of two concentric circles spherical conducting shells are r1 and r2 (r1<r2) .The change on the outer shell is q. The charge on the inner shell which is connected to the earth is
Two concentric, thin metallic spherical shells of radii R1andR2(R1>R2) bear charges Q1 andQ2 respectively. Then the potential at radius ‘r’ between R1 and R2will be 14πϵ0 times
