A heavy brass-sphere is hung from a sprial spring and it exectues vertical vibrations vibrations with period `T`. The ball is now immersed in nonvicous liquid with a density one-tenth that of brass. When set into verical vibrations with the sphere remaining inside liquid all the time, the period will be:-

A

`[9/10]T`

B

`Tsqrt(((10)/(9)))`

C

Uncharged

D

`Tsqrt(((9)/(10)))`

Text Solution

Verified by Experts

The correct Answer is:
B
Time period for spring block system is
`T = 2pisqrt((m)/(k))` does not effected.

A simple pendulum has a time period T in vacuum. Its time period when it is completely immersed in a liquid of density one-eight of the density of material of the bob is

A block of mss m is placed on a level frictionless table. The block is attached to a horizontally aligned spring fixed with its other end and is vibrating in a horizontal with the pariod T . Suddenly at the instant of time when the spring comes to the position of euilibrium and becomes unstretched the block disconnects form the spring and continues sliding across the frictionless surface away from the until it encounters loop of radius R . What must be the amplitude of vibrations of the block s on the spring in order for the block to complets one loop without falling down?
