A ball falling in a lake of depth 200 m shows 0.1 % decrease in its volume at the bottom. What is the bulk modulus of the material of the ball?

• A

  $19.6\times {10}^8\mathrm{N}/{\mathrm{m}}^2$

• B

  $19.6\times {10}^{-10}\mathrm{N}/{\mathrm{m}}^2$

• C

  $19.6\times {10}^{10}\mathrm{N}/{\mathrm{m}}^2$

• D

  $19.6\times {10}^{-8}\mathrm{N}/{\mathrm{m}}^2$
