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

A

`16xx10^(-32)J`

B

`31xx10^(-26)J`

C

`4xx10^(-10)J`

D

`32xx10^(-32)J`

Text Solution

Verified by Experts

The correct Answer is:
D
`"Here, "q=8xx10^(-18)C, C=100muF=10^(-4)F`
`V=(q)/(C)=(8xx10^(-18))/(10^(-4))=8xx10^(-14)V`
`"Work done "=(1)/(2)qV=(1)/(2)xx8xx10^(-18)xx8xx10^(-14)`
`=32xx10^(-32)J`
