Question

The work done to transport $20C$ charge from points $A$ to another point $B$ over distance of $0.2m$ is $2$ joule The potential difference across $AB$ is

• A. $2\times {10}^{-2}V$
• B. $4\times {10}^{-1}V$
• C. $1\times {10}^{-1}V$
• D. $10V$

Answer 1

The correct option is D $10V$

given$:$

charge $=20C$

work done$=2J$

We know$,$

$V=\frac{W}{Q}$

$=\frac{20}{2}$

$=10V$

Hence$,$

option $\left(D\right)$ is correct answer.
