Question

Bulk modulus for rubber is `9.8xx10^(8)Nm^(-2)`. To what depth should a rubber ball be taken in a take so that its volume is decreased by `0.1%`

Answer 1

`K=((/_P)V)/(/_V)` or `(K/_V)/V`
Let `h` be the required depth and the desity of water be `rho`.
Then
`hrhog=(K/_V)/V`
or `h=(K/_V)/(rhogV)=(9.8xx10^(8)xx0.1)/(10^(3)xx9.8xx100)=100m`
