When a sphere is taken to the bottom of a sea of depth 1 km, it contracts in volume by $0.01 \%$, then the bulk modulus of the material of the sphere is (Acceleration due to gravity $=10 \mathrm{~m} \mathrm{~s}^{-2}$ )

• A

  $10 \times 10^6 \mathrm{~N} \mathrm{~m}^{-2}$
• B

  $1.2 \times 10^{10} \mathrm{~N} \mathrm{~m}^{-2}$
• Correct answer
  C

  $10 \times 10^{10} \mathrm{~N} \mathrm{~m}^{-2}$
• D

  $10 \times 10^{11} \mathrm{~N} \mathrm{~m}^{-2}$

Hence, the correct answer is option: 'C'.
