Potential at a point in a field is defined as the amount of work done in bringing a unit positive test charge (q) from to that point along any arbitrary path Potential, V=(W/q0) or Work done, W=qV

Q. A charge $Q$ is placed at the origin. The electric potential due to this charge at a given point in space is $V$ . The work done by an external force in bringing another charge $q$ from infinity up to the point is

$\frac{V}{q}$

$V q$

$V + q$

$V$

Potential at a point in a field is defined as the amount of work done in bringing a unit positive test charge $(q)$ from to that point along any arbitrary path Potential,
$V = \frac{W}{q _{0}}$ or Work done, $W = q V$
