NEET Physics Electric Potential MCQ Question
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?
U = (1 / (4πε0)) * (q1q2 / r12)
U = (1 / (2πε0)) * (q1q2 / r12)
U = (4πε0) * (q1q2 / r12)
U = (1 / (4πε0)) * (q1 + q2 / r12)
Correct Answer
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.
