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

A

`-19xx10^(-17)J`

B

`9.60 xx 10^(-17)J`

C

`-2.24 xx 10^(-16)J`

D

`2.24 xx 10^(-16)J`

Text Solution

Verified by Experts

The correct Answer is:
D
`W=Q dV=Q(V_q-V_p)=-100 times (1.6 times 10^-19) times (-4-10)= pm 100 times 1.6 times 10^-19 times times 14= pm 2.24 times 10^-16 J`
