NEET Physics Electric Potential MCQ Question
Type: MCQ-diagram based-Easy-Class 12
Consider a system with two point charges q1 and q2 separated by a distance r12. Which expression correctly represents the potential energy U of this system?
A
U = (1 / (4πε0)) * (q1q2 / r12)
B
U = (1 / (2πε0)) * (q1q2 / r12)
C
U = (4πε0) * (q1q2 / r12)
D
U = (1 / (4πε0)) * (q1 + q2 / r12)
Correct Answer
Option A
Detailed Explanation
The potential energy U of a system of two point charges is given by the equation U = (1 / (4πε0)) * (q1q2 / r12), as derived from the conservative nature of electrostatic forces.
