When a rubber ball is taken to a depth of _______ m in deep sea, its volume decreases by 0 . 5 % (The bulk modulus of rubber = 9 . 8 × 10 8 N m - 2 Density of sea water = 10 3 kg m - 3 , g = 9 . 8 m s - 2 )

Correct answer

0

Step-by-step solution

- d V V = 0 . 5 100 = 0 . 005 B = - d P d V V = ρ g h - d V V 9 . 8 × 10 8 = 10 3 × 9 . 8 × h 5 × 10 - 3 ⇒ h = 500   m
