The work done in placing a charge of `8xx10^-18` coulomb on a condenser of capacity 100 micro-farad is

A

`3.1 xx 10^(-26) J`

B

`4 xx 10^(-10) J`

C

`32 xx 10^(-32) J`

D

`16 xx 10^(-32) J`

Text Solution

Verified by Experts

The correct Answer is:
B
`W = (1)/(2)Cv^(2) = (1)/(2)(q^(2))/(C )`
`= (1)/(2) xx ((8xx10^(-18))^(2))/(100xx10^(-6))`
`= (1)/(2) xx (64xx10^(-36))/(100xx10^(-6))`
`= 32 xx 10^(-32)J`
