Question

A FORCE OF 100 N acts on a body of 2 kg for 10S .then change in momentum of the body is :- A) 100Ns B) 250Ns C) 500 Ns D) 1000Ns Plz don't just say the option as I know it but I JUST NEED TO GET TYE STEPS TO GET INYO THE OPTION ....

Answer 1

Answer:

Given : F=100 N m=2 kg t=10 s

Change in momentum of the body m(Δv)=F.t

where Δv is the change in velocity.

⟹ 2×Δv=100×10

⟹ Δv=500 m/s

Answer 2

Correct answer is (c) 500 Ns
