Physics-Work-Energy Theorem
NEET Physics Work-Energy Theorem MCQ Question
Type: MCQ-numerical-Easy-Class 11
A particle of mass 2 kg is moving under the influence of a conservative force. If it is released from rest at a height of 5 m on a frictionless inclined plane, what will be its kinetic energy at the bottom of the plane?
A
100 J
B
50 J
C
20 J
D
10 J
Correct Answer
Option A
Detailed Explanation
The work done by the gravitational force is converted into kinetic energy. Using the work-energy theorem, the kinetic energy at the bottom is mgh = 2 * 10 * 5 = 100 J.
