Question

A spherical ball contracts in volume by `0.02%` when subjected to a normal uniform pressure of 200 atmospheres. Then Bulk modulus (in `N//m^(2)`) of the material of the ball is
(Atomospheric pressure `=10^(5)N//m^(2)`)
A. `10^(9)`
B. `10^(10)`
C. `10^(11)`
D. `10^(12)`

Answer 1

Correct Answer - B
`K=(dp)/((dv)/(v))=(200xx10^(5))/(2xx10^(-3))=100xx10^(8) =10^(10)`.
