Physics of Sound

  1. The period of oscillation of a mass M suspended from a spring of negligible mass is T. If along with it another mass M is also suspended, the period of oscillation will now be​
    1. T
    2. T / √2
    3. 2T ​
    4. 2 T
Correct Option: D

T = 2π
m
K

T1
=
M1
T2M2

∴ T2 = T1 = T1
M2
2M
M1M

T2 = T12 = √2 T (where T1 = T)
