Question

A heavy brass sphere is hung from a spring and it executes vertical vibrations with period T. The sphere is now immersed in a non-viscous liquid with a density ${\frac{1}{10}}^{th}$ that of brass. When set into vertical vibrations with the sphere remaining inside liquid all the time, the time period will be:

• A. $\sqrt{\frac{9}{10}}T$
• B. $\sqrt{\frac{10}{9}}T$
• C. $\frac{9}{10}T$
• D. Unchanged

Answer 1

The correct option is D Unchanged

Time period of mass oscillating on a spring is independent of “g”.
