Two points P and Q are maintained at the potentials of 10V and -4V, respectively. The work done in moving 100 electrons from P to Q is:

A

`-9.60xx10^(-17)J`

B

`9.60xx10^(-17)J`

C

`-2.24xx10^(-16)J`

D

`2.24xx10^(-16)J`

Text Solution

Verified by Experts

The correct Answer is:
D
`W=qV_(QP)=100xx(-1.6xx10^(-19))xx(-4-10)`
