A raindrop falling from a height `h` above ground, attains a near terminal velocity when it has fallen through a height `(3//4)h`. Which of the diagrams shown in figure correctly shows the change in kinetic and potential energy of the drop during its fall up to the ground ?

Options

A.
B.
C.
D.

Answer

B

Explanation

The potential energy of the drop is decreasing continuously . The velocity of drop ( nad hence KE ) increases in the beginning and when the dro attains terminal velocity , KE also becomes constant as shown in option (b)
