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

Potential difference is a direct measure of work accomplished or required per unit of charge.

2. Formula:

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

3. Solution:

  • Given work energy: \( W = 600 \text{ J} \).


  • Given charge: \( q = 2 \text{ C} \).


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


4. Why other options are incorrect:

Option A results from incorrectly multiplying 600 by 2 instead of dividing.
