Question

A ball falling in a lake of depth `200 m` shows a decrease of `0.1% ` in its volume at the bottom. The bulk modulus of elasticity of the material of the ball is (take `g = 10 ms^(-2)`)
A. `10^8`
B. `2xx10^8`
C. `10^9`
D. `2xx10^9`

Answer 1

Correct Answer - D
`K=(triangleP)/((triangleV)/(V))=(hrhog)/((triangleV)/(V))=(200xx10^3xx10)/((0.1)/(100))=2xx10^9`
