Question

What is the ratio of inertia of two bodies A and B having masses 10kg and 50kg respectively? Why?

Answer 1

Potential energy = mgh

P.E for body A= 10kg*gh=10gh

P.E for body B = 20kg*gh=20gh

So, clearly P.E do body B is greater than that of A.

Answer 2

ma /mb = 10/50 = 1/5 I think it is right
