NEET Physics Work-Energy Theorem MCQ Question
Consider a diagram showing a raindrop of mass 1.00 g falling from a height of 1.00 km and hitting the ground with a speed of 50.0 m/s. Which of the following quantities represents the work done by the resistive force acting on the raindrop?
-8.75 J
10.0 J
25 J
0 J
Correct Answer
Detailed Explanation
The work done by the resistive force is calculated using the work-energy theorem: W_r = ΔK - W_g. From the problem, this gives W_r = 1.25 J - 10.0 J = -8.75 J.
