When a rubber ball is taken to a depth of \_\_\_\_ m in deep sea, its volume decreases by $\displaystyle 0.5 \%$.
(The bulk modulus of rubber $\displaystyle =9.8 \times 10^8 \mathrm{Nm}^{-2}$
Density of sea water $\displaystyle =10^3 \mathrm{kgm}^{-3}$
$$\left.\mathrm{g}=9.8 \mathrm{~m} / \mathrm{s}^2\right)
$$
