MHT CET 2023 Physics question
A mass 'M' is suspended from a light spring. An additional mass M added extends the spring further by a distance 'x'. Now the combined mass will oscillate on the spring with period T =
Answer: (B)
Solution
The extra mass stretches the spring by , so the spring constant is . After adding the oscillating mass is , and the period of a spring-mass system is
