A rain drop of radius 2 mm falls from a height of 500 m above the ground. It falls with decreasing acceleration (due to viscous resistance of the air) until at half its original height, it attains its maximum (terminal) speed, and moves with uniform speed thereafter.

What is the work done by the resistive force in the entire journey if its speed on reaching the ground is 10 m s-^1 ?
