The radius of gyration is
Explanation:
Given that,
Mass of each four solid balls = m
Radius = r
Radius of ring = 2r
Mass of ring = 2m
We need to calculate the moment of inertia
Using formula of moment of inertia
I=moment of inertia of the ring+ moment of inertia of the ball
Put the value into the formula
We need to calculate the radius of gyration
Using formula of radius of gyration
Put the value into the formula
Hence, The radius of gyration is
