Question:

The work done in moving a point charge, $2 \mu C$ between two points between which the potential difference is 50 V is:

Options:

$10^{-4} J$

$10^{-5} J$

$10^{-6} J$

$10^{-7} J$

Correct Answer:

$10^{-4} J$

Explanation:

The correct answer is Option (1) → $10^{-4} J$

The work done, W in moving a point charge q between two points with potential difference ΔV is -

$W=qΔV$

$W=2×10^{-6}×50$

$=100×10^{-6}=10^{-4}J$
