Bulk modulus of elasticity of rubber is `10^(9)N//m^(2)`. If it is taken down to a 100 m deep lake, then decrease in its volume will be ` " "(g=10m//s^(2))`

Options

A. `0.1%`
B. `0.2%`
C. `1%`
D. `2%`

Answer

A

Explanation

`K=v (dp)/(dv)`
`therefore (dv)/(v)=(dp)/(k)=(h rho g)/(k)`
`=(100xx10^(3)xx10)/(10^(9)) =10^(-3)=0.1%`.
