Solution
Correct Answer:
q ΔV
- Definition of Potential Difference (ΔV): This is the work done per unit charge in moving a charge from one point to another.
- Relationship: W=q×ΔV.
- Explanation: In an electrostatic field, work done is path-independent and depends only on the initial and final potentials.
- Result: For a charge q moving through a potential difference ΔV, the total work required is qΔV.
This medium difficulty physics question is from the chapter electrostatics, covering the topic of work and potential difference. It appeared in the 2025 exam.
