Force of inertia = ma
Let the masses be 1x and 5x
Force of inertia for 1st body= 1x * a
Force of inertia for 2nd = 5x * a
Ratio= x * a / 5x * a = 1:5

I will give you a two method to your question... 1st method; inertia is measured by in terms of mass only... so mass equal inertia... so 1:5 option A is correct.. 2nd method; force of inertia=m×a let the masses be 1x and 5x for inertia of 1st body=1x × a for inertia of 2nd body=5x × a total inertia ratio= 1xa÷5xa so the ratio is 1:5...hence proved...hope u clear...!!👍

Two masses are in the ratio 1:5. What is ratio of their inertia?a)1:5b...
Given: Ratio of masses = 1:5

Inertia is directly proportional to the mass of an object. Therefore, we can say that the ratio of their inertia will be the same as the ratio of their masses.

Ratio of inertia = Ratio of masses = 1:5

Hence, option A (1:5) is the correct answer.
