Physics-Potential Difference
NEET Physics Potential Difference MCQ Question
Type: MCQ-numerical-Hard-Class 12
Calculate the work done by an external force in moving a charge of 5 µC from point R to point P if the potential difference V_P - V_R is 100 V.
A
0.5 mJ
B
0.5 µJ
C
5 mJ
D
5 µJ
Correct Answer
Option A
Detailed Explanation
The work done by an external force is given by the product of the charge and the potential difference: q(V_P - V_R). Thus, W = 5 x 10^-6 C * 100 V = 0.5 mJ.
