The capacitance of spherical conductor of radius 10 m is

Options

A. 10 F
B. `9xx10^(9)F`
C. `(1)/(9xx10^(8))F`
D. `(1)/(9xx10^(9))F`

Answer

C

Explanation

As, capacitance of spherical conductor,
`C=4pi epsilon_(0)r=(1)/(9xx10^(9))xx10(because 4pi epsilon_(0)=(1)/(9xx10^(9)))`
`=(1)/(9xx10^(8))F`
