NEET Physics Electric Potential MCQ Question
Type: MCQ-numerical-Hard-Class 12
If two charges of q1 = 3 μC and q2 = 6 μC are separated by a distance of r12 = 0.5 m in a vacuum, what is the electrostatic potential energy of the system? (Use ε0 = 8.854 × 10^-12 C^2/N·m^2)
A
0.324 J
B
0.216 J
C
0.108 J
D
0.432 J
Correct Answer
Option A
Detailed Explanation
Using U = (1 / (4πε0)) * (q1 * q2 / r12), substituting the given values yields U = 0.324 J, considering the formula from the NCERT context.
