Question

The bulk modulus of water is `2.0xx10^(9) N//m^(2)`. The pressure required to increase the density of water by `0.1%` is
A. `2xx10^(9)N//m^(2)`
B. `2x10^(8)N//m^(2)`
C. `2xx10^(N)//m^(2)`
D. `2xx10^(4)N//m^(2)`

Answer 1

Correct Answer - C
The density would increase by `0.1%` if the volume decreases by `0.1 %`
`K=(/_P)/(/_V//V)`
`/_P=K(/_V)/V=2xx10^(9)xx0.1/100=2xx10^(6)N//m^(2)`
