Question

A rubberball is taken to depth of 1 km inside water so that its volume reduces by 0.05%. What is the bulk modulus of rubber

Answer 1

bulk modulus is given by PV/∆V

p=rho x g x h
(i am assuming rho of water 1000)
P=1000 x 10 x 1000
=10^7N/m^2
∆V/V=0.05/100=5 x 10^-4

bulk modulus is

10^7/(5 x 10^-4)
=2 x 10^10
