The work done in moving a point charge, \( 2\,\mu\mathrm{C} \) between two points between which the potential difference is 50 V is:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → \( 10^{-4}\,\mathrm{J} \)
The potential difference between two points is the work done per unit charge in moving a charge between them, so \( W = q\,\Delta V \).
\( q = 2\,\mu\mathrm{C} = 2\times10^{-6}\,\mathrm{C} \)
\( W = q\,\Delta V = 2\times10^{-6}\,\mathrm{C}\times50\,\mathrm{V} = 10^{-4}\,\mathrm{J} \)
