A balloon was moving upwards with a uniform velocity of $10 \mathrm{m} {\mathrm{s}}^{-1}$. An object of finite mass is dropped from the balloon when it was at a height of $75 \mathrm{m}$ from the ground level. The height of the balloon from the ground when object strikes the ground was around: (takes the value of $\mathrm{g}$ as $10 \mathrm{m} {\mathrm{s}}^{-2}$)

• A

  $300 \mathrm{m}$
• B

  $200 \mathrm{m}$
• Correct answer
  C

  $125 \mathrm{m}$
• D

  $250 \mathrm{m}$

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