Capacitance of a capacitor 100 `mu` F. The work is done for depositing chargc `8 xx 10^(-18)` C on it will be .........

A

`16.10^(23) J`

B

`3.1xx10^(-26)` J

C

`4xx10^(-10)` J

D

`32 xx10^(-32)` J

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
`W = U_(2) -U_(1)`
`= (Q^(2))/(2C) -0`
`=((8xx10^(-18))^(2))/(2xx100xx10^(-6))=(64xx10^(-36+4))/(2)`
`:. W = 32 xx10^(-32)` J
