Question

The mass of two substances are 25g and 89g respectively.If their kinetic energies are same then the ratio of their moments is

Answer 1

Here,
K1= P1 square /2m1
K2= P2 square /2m2

Here k1 and k2 are kinetic energy
P1 and P2 are momentums
M1 and m2 are masses

As k1=k2
P1 square/m1 = P2 square/m2
P1/P2 = root over M2/mq

P1/P2 = root over 89/25

Hope you get your answer.
