NEET Physics Potential Energy MCQ Question
Four particles each of mass m are placed at the vertices of a square of side l. The potential energy of the system is
-√2Gm²/l (2 - 1/√2)
-√2Gm²/l (√2 + 1/√2)
-2Gm²/l (√2 - 1/√2)
2Gm²/l (2 + 1/√2)
Correct Answer
Detailed Explanation
The potential energy of a system of particles is calculated by considering the gravitational potential energy between each pair of particles. The symmetry of the square and the distances between particles lead to the given expression.
