JEE Main 2024 Physics question
Four particles each of mass 1 kg are placed at four corners of a square of side 2 m. Moment of inertia of system about an axis perpendicular to its plane and passing through one of its vertex is kgm².
Answer: 16
Solution
I = 2(Ma²) + M(√2 a)² = 4Ma² = 4 × 1 × 4 = 16 kg m².
