Show full solutionCorrect option: B
Correct answer
BImpulse will be same for both the cases but the average force will be different.
Step-by-step explanation
Impulse Change in momentum
Therefore, in both the cases the impulse is same.
Average force is defined as,
Since the time in the two cases is different, the average force will be different.
