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.
