- 1.0 V
- 2.0 V
- 2.5 V
- 1.5 V
- 3.0 V
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Work done $W$ to move a charge $q$ is $W = q(V_Q - V_P)$.
Step 2: Analysis
Given $W = 10\ J$, $q = 5\ C$, and $V_P = 0.5\ V$.
Step 3: Calculation
$10 = 5(V_Q - 0.5) \implies 2 = V_Q - 0.5 \implies V_Q = 2.5\ V$. Final Answer: (C)
