NEET Physics Work-Energy Theorem MCQ Question
A diagram shows 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 best describes the work done by the resistive force during the fall?
The resistive force does negative work of -8.75 J.
The resistive force does positive work of 8.75 J.
The resistive force does no work as it is a conservative force.
The resistive force does work equal to the gravitational force, 10.0 J.
Correct Answer
Detailed Explanation
The work-energy theorem states that the work done by the resistive force is the change in kinetic energy minus the work done by gravity, which is -8.75 J.
