Capacitance of spherical capacitor is 1 ...

Capacitance of spherical capacitor is 1 `muF`, so its diameter = ........ m. `[(1)/(4pi epsilon_(0))=9xx10^(9) SI]`

A

`1.8`

B

18

C

`1.8 xx10^(3)`

D

`1.8xx10^(4)`

Text Solution

Verified by Experts

The correct Answer is:
A, D
`C=(R)/(k)`
`:. R = kC = 9xx10^(9)xx1xx10^(-6)=9xx10^(3) `
`:.` diameter =`2R = 2 xx9 xx10^(3)= 1.8xx10^(4)` m
