alleryThe work done in bringing a charge q from infinity to a point where the potential is V is
AqV²
Bq²V
CqV
DV/q
Answer & Solution
Correct answer: C. qV
1. W = ∫ F·dl; equivalently W = q × (V_final − V_initial).
2. V at infinity = 0 by convention, so W = q × V.
3. Other options are dimensionally inconsistent with energy.
