Question

A ball falling in a lake of depth 200m shown 0.1% decrease in its volume at the bottom .What is the bulk modulus of the materialof the ball
A. `19.6xx10^(8) Nm^(-2)`
B. `19.6xx 10^(9) Nm^(-2)`
C. `19.6xx10^(10) Nm^(-2)`
D. `19.6 xx 10^(12) Nm^(-2)`

Answer 1

Correct Answer - A
(a) Bulk modulus of the mateial , `B=(Deltap)/(DeltaV//V)=(hrhog)/(0.1//100)`
`(200xx10^(3)xx9.8)/(1//1000)=19.6xx10^(8) Nm^(-2)`
