Verified Solution • 2025–26 Session moderate

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

\times

10⁸ Nm^{$-$ 2}, Density of sea water = 10³ kgm^{$-$ 3}, g = 9.8 m/s²)

Accepted Answer

B = - \frac{Δ P}{(\frac{Δ V}{V})} = - \frac{ρ g h}{(\frac{Δ V}{V})}

- \frac{B \frac{Δ V}{V}}{ρ g} = h

\frac{9.8 \times 10^{8} \times 0.5}{100 \times 10^{3} \times 9.8} = h

h = 500
