Question

A ball is falling in a lake of depth 200m shows a decease of 0.1 percentage in its volume of the bottom the bulk modulus of equality of material of the ball is (take g=10ms-12

Answer 1

B=-PV/dv

P= p g h

P=1000× 10×200=2×10^6

dv/v=0.1%= -0.001

B=-2×10^6/-0.001=+2×10^9

I hope this helps ( ╹▽╹ )
