A solid copper sphere is suspended from a massless spring. The time period of oscillation of the system is 4 s. The sphere is now completely immersed in a liquid whose density is 1/8the that of brass. The sphere remains in liquid during oscillation. Now, the time period is

A

4 s

B

2 s

C

3 s

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
Since, `T=2pisqrt((m)/(k))`
Here, m and k remain constant.
Hence, T remains constant.
