Type: MCQ-numerical-Medium-Class 11
The force F acting on a particle of mass m is indicated by the force-time graph shown below. The change in momentum of the particle over the time interval from zero to 8 s is
A
24 Ns
B
20 Ns
C
12 Ns
D
6 Ns
Correct Answer
Option A
Detailed Explanation
The change in momentum is the area under the force-time graph. The area is a trapezoid with a base of 8 s and heights of 3 N and −3 N, giving a total area of 24 Ns.
