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

A

`32xx10^(-32)`J

B

`16xx10^(-32)`J

C

`3.1xx10^(-26)`J

D

`4xx10^(-10)`J

Text Solution

Verified by Experts

The correct Answer is:
A
Work done, `W = (q^(2))/(2C) = (8xx10^(-18))^(2)/(2xx100xx10^(-6))`
`= 32xx10^(-32) J`
