A stone is dropped from the top of a tall building and after 2 seconds another stone is thrown vertically downwards with a velocity $5 \mathrm{~ms}^{-1}$ from the same point. Then the distance from the top of the building at which second stone overtakes the first is ____ $\left(\mathrm{g}=10 \mathrm{~ms}^{-2}\right)$

• A

  $0.222 \mathrm{~m}$
• Correct answer
  B

  $2.22 \mathrm{~m}$
• C

  $22.2 \mathrm{~m}$
• D

  $222 \mathrm{~m}$

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