NEET Physics (general) MCQ Question
Type: MCQ-numerical-Hard-Class 11
A particle of mass 2 kg is moving along a straight line under the influence of a variable force F(x). If the work done by the force as the particle moves from position x = 0 to x = 3 m is 18 J, what is the change in kinetic energy of the particle?
A
18 J
B
9 J
C
36 J
D
0 J
Correct Answer
Option A
Detailed Explanation
According to the work-energy theorem, the change in kinetic energy of a particle is equal to the work done on it by the net force. Therefore, the change in kinetic energy is equal to 18 J.
