The correct answer to the question is : [tex]10^{-2}\ N.s[/tex]
EXPLANATION:
As per the question, the force involved in the collision F = [tex]1.0\times 10^2\ N.[/tex].
The duration of impact is given as t = [tex]1.0\times 10^{-4}\ s[/tex].
We are asked to calculate the change in momentum.
We know that the change in momentum is equal to the impulse of a body .
The impulse of a body is defined as the product of force with time.
Hence, impulse = force × time
= F × t
= [tex]1.0\times 10^2\ N\times 1.0\times 10^{-4}\ s[/tex]
= [tex]10^{-2}\ N.s[/tex] [ans]
Hence, the change in momentum is [tex]10^{-2}\ N.s[/tex]
