Question

Q9. The formulae of potential
difference between two points Vis
1 point
(a) W/a
(b) wxq
(c) q/w
(d) None​

Answer 1

Answer:

W/q

Explanation:

In electric field, test charges are either attracted or gone opposite to that.

In order to overcome that massive force we apply almost equal force. We compare this potential with other(placed at infinity,  where PD is assumed as 0).

And the work done by us(or external force) per charge is called the potential difference.

So,

⇒ P.D = workdone per charge

          = wokrdone / charge

          = W/q
