Consider a drop of rain water having mass $1 \mathrm{g}$ falling from a height of $1 \mathrm{km}$. It hits the ground with a speed of $50\mathrm{ }\mathrm{m} {\mathrm{s}}^{-1}$. Take $g$ constant with a value $10\mathrm{ m} {\mathrm{s}}^{-2}$. The work done by the (i) gravitational force and the (ii) resistive force of air is

• A

  $\begin{array}{cc}\left(i\right)-10 \mathrm{J}& \left(ii\right)-8.25 \mathrm{J}\end{array}$
• B

  $\begin{array}{cc}\left(i\right) 1.25 \mathrm{J}& \left(ii\right)-8.25 \mathrm{J}\end{array}$
• C

  $\begin{array}{cc}\left(i\right) 100 \mathrm{J}& \left(ii\right) 8.75 \mathrm{J}\end{array}$
• Correct answer
  D

  $\begin{array}{cc}\left(i\right) 10 \mathrm{J}& \left(ii\right)-8.75 \mathrm{J}\end{array}$

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