On moving a charge of ` 20 ` coulomb by ` 2 cm`, ` 2J` of work is done , the potential difference between the points is .

A

`0.1 V`

B

`8 V`

C

`2 V`

D

`0.5 V`

Text Solution

Verified by Experts

The correct Answer is:
A
Work done= (charge) (P.D.)
`P.D=("Work done")/("Charge")=(2J)/(20C)=0.1 V`
