GIVEN THAT :-

• $&#10144$ The electric potentials at points P1 and P2 are V1 and V2 respectively.

• $&#10144$ A point electric charge - q is brought from P1 to P2 by an external agent .

FORMULA:-

• $&#10144$ Potential difference between two points

$&#10144 \: v = \frac{w}{q}$

where,

v = potential difference

w = work done

q = charge

SOLUTIONS

• $&#10144$ potential difference = V2-V1

• Let V2 - V1 = V

Now work done to bring q charge from point p1 to p2

$&#10230 \: \: V = \frac{w}{q} \: \\ \\ &#10230 \: \: w = Vq$
