NEET Physics Electric Potential MCQ Question
Type: MCQ-numerical-Easy-Class 12
Two point charges q1 = 3 μC and q2 = -3 μC are placed 0.1 m apart in vacuum. What is the electric potential energy of this system?
A
0 J
B
-0.81 J
C
0.81 J
D
-0.27 J
Correct Answer
Option B
Detailed Explanation
Using the formula for potential energy U = (1/(4πε0)) * (q1 * q2) / r, substituting the values, we get U = -(9 × 10^9) * (9 × 10^-6) / 0.1 = -0.81 J.
