Question

Calculate the amount of work done in carrying a charge of $5mC$ against a potential difference of $100volt$.

• A. $0.5J$
• B. $50J$
• C. $5J$
• D. None

Answer 1

The correct option is A $0.5J$

Work done =$Q\Delta V$ = charge $\times$ potential difference

Here, $Q=5\times {10}^{-3}C$, $V=100volt$

So, work done = $Q\Delta V=5\times {10}^{-3}\times 100J=0.5J$
