Question

A thin uniform circular disc of mass M and radius R is rotating in a horizontal plane about an axis passing through its center and perpendicular to its plane with an angular velocity omega. Now two particles each of mass m are placed on its perimeter along a diameter along a diameter. Find the new angular velocity. If m=M//2, find the percentage change in the angular velocity.

Answer 1

it is because of velocity. when velocity increases inertia also increases
