Question

Capacity of a spherical conductor of radius 10 m is

Answer 1

Answer:

Capacitance (in F) of a spherical conductor with radius 1 m is

10-3

1.1 X 10-10

9 X 10-9

10-6

Answer

Capacitance of a spherical conductor is given by

C = 4πεor

where r = radius of spherical conductor

C = 4πεo = 1/(9x109) = 1.1 x 10-10 F

The correct option is B.
