Question

(C) The formula of Capacitance of a spherical conductor is :
(a) Cameo
(b) C =41 ER
(c) C =471 €
(d) C =41 Eo R? R2​

Answer 1

Explanation:

The capacitance of any sphere (C = 4πε0R), whether hollow or solid, will be the same if the surrounding medium is the same. Again, if the surrounding medium is air, then capacitance C = 4πε0R, where R = radius of the sphere. The above two spheres have an equal radius.
