Question

The capacity of a spherical conductor is 1 micro farad then its diameter would be

Answer 1

Hello Dear,

◆ Answer -

d = 18000 m

◆ Explaination -

# Given -

C = 1 μF = 10^-6 F

# Solution -

Capacitance of isolated spherical conductor is given by formula -

C = 4πεr

10^-6 = 4π × 8.85×10^-12 × r

r = 10^-6 / (1.111×10^-10)

r = 9×10^3 m

r = 9000 m

Therefore, diameter of sphere would be -

d = 2r

d = 2×9000

d = 18000 m

Hope this helps you..
