Application +4 | -1

Two thin uniform circular rings each of radius 10 cm and mass 0.1 kg are arranged such that they have a common centre and their planes are perpendicular to each other. The moment of inertia of this system about an axis passing through their common centre and perpendicular to the plane of one of the rings in

kg\,{cm^2}

is

View answer and explanation

Correct option: C

15

Option C (15) is correct. The moment of inertia of the system is the sum of the moments of inertia of each ring.
