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