Answer:
0.0247212 Joules
-0.0247212 Joules
Explanation:
Potential energy
a) The work done by the gravitational force is given by the potential energy that the body has at the start of the fall.
Work done is considered as positive if the force which is being applied is in the direction of motion.
Hence, the work done on the raindrop by the gravitational force is 0.0247212 Joules
b) As the drop is falling the air resistance provides an opposite force this means the sign of the work done will be negative.
So, the work done on the raindrop by air resistance is -0.0247212 Joules
