When a mass M is suspended from a spring...

When a mass M is suspended from a spring, its period of oscillation is 2 second. If a mass 4 M is suspended from the same spring, then its period of oscillation will be

A

1 s

B

2 s

C

3 s

D

4 s

Text Solution

Verified by Experts

The correct Answer is:
D
`T=2pisqrt(m/k)`
`implies (T_(2))/(T_(1))=sqrt((m_(2))/(m_(1)))=2`
`implies T_(2)=2xx2=4sec`.
