2. Electric Potential and Capacitance

easy

As shown in figure, on bringing a charge $Q$ from point $A$ to $B$ and from $B$ to $C$, the work done are $2\, joule$ and $-3\, joule$ respectively. The work done to bring the charge from $C$ to $A$ is

A

$-1$

B

$1$

C

$2$

D

$5$

Solution

$W_{AB} + W_{BC} + W_{CA} = 0$ (Conservative force), $-3 + 2 + W_{CA} = 0$ $ \Rightarrow $ $W_{CA} = 1\, Joule$
