Answer 2

Question :

28J work is done in moving a positive charge of 4C between two pionts. find the potential difference between the points?

Theory :

•potential difference:

The potential difference between two points in electric field is defined as the amount of work done in bringing a unit positive charge from one point to the other point against the electric field.

⇒The potential difference between any two points A and B is given by:

${\purple{\boxed{\large{\bold{V_{B}-V_{A}=\frac{W_{AB}}{q_{o}}}}}}}$

Solution :

Given : Work done ,W = 28 J

Charge,q =4C

W =qΔV

⇒28=4×ΔV

⇒ΔV=28/4

⇒ΔV =7 J/C

Therefore,the potential difference between points is 7J/C

More About Potential difference :

1) SI unit is jolue/coulomb.

2) Dimensions are [$ML{}^{2}T{}^{-3}A{}^{-1}$ ]

3) It is an absolute quantity.

4) Potential difference between two points is path dependent and depends only on the position of points.

4) Electric potential is theoretically zero at infinite and practically zero at earth's surface.
