When a pressure of 100 atmosphere is applied on a spherical ball, then its volume reduces to `0.01%`. The bulk modulus of the material of the rubber in dyne/`cm^2` is

Options

A. `10xx10^(12)`
B. `100xx10^(12)`
C. `1xx10^(12)`
D. `20xx10^(12)`

Answer

C

Explanation

(c) `because` Bulk modulus of the material of the rubber
`B=(Deltap)/(DeltaV//V)=(100)/(0.01//100)=10^(6) "atm" =10^(11) Nm^(-2)`
`=10^(12)` dyne `cm^(-2)`
