NEET Physics Friction MCQ Question
A ball is rolling on a horizontal surface and comes to a stop after 10 meters due to friction. If the frictional force is 5 N, what is the work done by friction?
50 J
5 J
500 J
10 J
Correct Answer
Detailed Explanation
The work done by friction is calculated as the force multiplied by the distance over which it acts. Here, Work = Force x Distance = 5 N x 10 m = 50 J.
