A raindrop falling from a height h above ground attains a near terminal velocity when it has fallen through a height
. 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?
Text Solution
Verified by ExpertsB
: At a height h above the ground, PE of raindrop is maximum and KE = 0. As the raindrop falls its PE goes
above the ground. At this stage, rain drop has acquired near terminal velocity (=constant). Therefore, at this stage, KE tends to be constant. PE becomes zero when raindrop falls to the ground. Hence, option is most appropriate.
