Question

Two masses in the ratios 1:5. What is the ratios of their momentum?

Answer 1

1:5

As we know p=mv.So let the mass of first particle be m1 and it's momentum be p1 and mass of second particles be m2 whereas momentum be p2. Therefore p1/p2 =m1v/m2v =m1/m2

But as we know m1/m2=1/5

Therefore p1/p2 =1/5 , hence its ratio will be 1:5
