A raind drop starts falling from a heigh of `2km`. If falls with a continuously decreasing acceleration and attains its terminal velocity at a height of `1km`. The ratio of the work done by the gravitational force in the first halt to that in the second half of the drops journey is

A rain drop of radius 2mm falls from a height of 250 m above the ground. What is the work done by the gravitational force on the drop ?

A rain drop of radius 2 mm falls from a height of 500 m above the ground. It falls with decreasing acceleration until at half its original height, it attains its maximum speed and moves with uniform speed thereafter. What is the work done by the gravitational force on the drop in the first and second half of its journey? What is the work done by the resistive force in the entire journey, if its speed on reaching the ground is 10ms^(-1) ?

A rain drop of radius R falls from a height of H metre above the ground. The work done by the gravitational force is proportional to which one of the following?

A rain drop of radius 2mm, falls from a height of 500 m above the ground. It falls with decreasing acceleration due to viscous resistance of air until half its original height. It attains its maximum (terminal ) speed, and moves with uniform speed there after. What is the work done by the gravitational force on the drop in the first half and second half of its journey ? Take density of water =10^(3)kg//m^(3) . What is the work done by the resistive force in the entire journey if its speed on reaching the ground is 10ms^(-1) ?
