Find | $V_{B A}$ | if $12 J$ of work has to be done against an electric field to take a charge of $10^{- 2} C$ from $a$ to $b$ .

Solution

Potential difference $(V_{B A})$ between two points is defined as the work done per unit charge transferred from one point to another point in space.
Thus $V_{B A} = \frac{12}{10^{- 2}} = 1200 V$
