Bulk modulus of water is `2 xx 10^9 N m^-2`, The pressure required to increase the volume of water by 0.1% in `Nm^-2` is

Options

A. `2xx10^9`
B. `2xx10^0`
C. `2xx10^6`
D. `2xx10^4`

Answer

C

Explanation

Change in volume,` Delta V= 0.1%` of original volume
`=V xx 0.1/100 = Vxx10^(-3)`
Bulk modulus , `K=(Pv)/(DeltaV) =2xx10^(9)`
`therefore p=2xx10^(9)xx10^(-3) = 2xx10^(6) N//m^(2)`
