Question
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
Options
A.T
B.
C.2T
D.√2T
Solution
A mass M is suspended from a massless spring of constant k as shown figure (a). Then
Time period of oscillation is T = 2π
.......(i)
When a another mass M is also suspended with it as shown in figure (b).
Then Time period of oscillation is
T′ = 2π
√2T [using (i)]
Time period of oscillation is T = 2π
.......(i)When a another mass M is also suspended with it as shown in figure (b).
Then Time period of oscillation is
T′ = 2π
√2T [using (i)]
