NEET Physics Electric Potential MCQ Question
Consider a point charge of +2 μC at a distance of 0.5 m from another point charge of -3 μC. Calculate the electric potential energy of this configuration. (Use k = 9 × 10^9 Nm²/C²)
-108 J
-54 J
108 J
54 J
Correct Answer
Detailed Explanation
The electric potential energy U between two point charges q1 and q2 separated by a distance r is given by U = k * q1 * q2 / r. Substituting the given values, U = 9 × 10^9 * (2 × 10^-6 C) * (-3 × 10^-6 C) / 0.5 m = -54 J.
