Official Correct Choice:
Option C: 300 V
1. Concept:

Potential difference (Voltage) directly measures the energetic 'cost' of forcing a set amount of charge from one location to another.

2. Formula:

$$ V = \frac{W}{q} $$

3. Solution:

  • Given the total Work (Energy): \( W = 600 \text{ J} \).


  • Given the total Charge: \( q = 2 \text{ C} \).


  • Substitute and evaluate: \( V = \frac{600}{2} = 300 \text{ V} \).


4. Why other options are incorrect:

Option A involves mathematically multiplying the values instead of dividing. Option D implies moving along an equipotential surface where work is zero.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
