Question

$100J$ of work is done when $2\mu C$ charge is moved in an electric field between two points. The p.d. between the points is

• A. $2\times {10}^{-4}V$
• B. $2\times {10}^{-8}V$
• C. $2\times {10}^{-6}V$
• D. $5\times {10}^{7}V$

Answer 1

The correct option is D $5\times {10}^{7}V$

We know work done $=q\Delta V$
Where $\Delta V$ is change in potential $V_2-V_1$
$100=\Delta V\times 2\times {10}^{-6}$
$50\times {10}^6=\Delta V$
$\therefore p\cdot d=5\times {10}^{7}V$
