MHT CET 2025 Physics question
A mass suspended from a vertical spring performs S.H.M. of period 0.1 second. The spring is unstretched at the highest point of suspension. Maximum speed of the mass is (Gravitational acceleration g = 10 m/s)
Answer: (A)
Solution
The mass is released from rest at the highest point, where the spring is unstretched, so this point is an extreme position of the SHM. The equilibrium position is where , i.e. , so the amplitude is . Angular frequency: rad/s and
