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^(6) N//m^(2)`

B

`19.6xx10^(8) N//m^(2)`

C

`9.8xx10^(3) N//m^(2)`

D

`19.6xx10^(3) N//m^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`K = V(dP)/(dV) = (dP)/(dV//V) = (19.6 xx 10^(5))/(10^(-3))`
`dP = rho gh = 1000 xx 9.8 xx 200 = 19.6 xx 10^(5)`
