To what depth must a rubber


To what depth must a rubber ball be taken in deep sea so that its volume is decreased by 0.1%.


Bulk modulus of rubber = 9.8 × 108 N/m2

Density of sea water = 103 kg/m3

Percentage decrease in volume = 0.1%

Change in pressure, p = hρg

B = ∆P/(∆V/V)

∆P = hρg

h = 100 m
