Find V(ba), if 12 J of work has to be do...

Find `V_(ba)`, if `12 J` of work has to be done against an electric field to take a charge of `10^-2` C from a to b.

A

`120 V`

B

`-250 V`

C

`1200 V`

D

`-120 V`

Text Solution

Verified by Experts

The correct Answer is:
C
`W_(ab)=/_\U_(a-b)=U_b-U_a=q(V_b-V_a)=qV_(ba)`
`: V_(ba)=W_(ab)/q=12/10^-2=1200V`
