Problem on rotation

An e q u i l a t e r a l A B C equilateral~ABC formed from a uniform wire has two small identical beads initially located at A A . The triangle is set rotating about the vertical axis A O AO . Then the beads are released from rest simultaneously and allowed to slide down, one along A B AB and the other along A C AC as shown. Neglecting frictional effects, the quantities that are conserved as the beads slide down are

total angular momentum and total energy total angular momentum and moment of inertia about the axis of rotation angular velocity and total energy angular velocity and moment of inertia about the axis of rotation

For making it higher level problem and more interesting & For Playing with physics for fun ... You can make changes in this question Like "Place this plank on ground andd then frame an Application based question on this situation Like as JEE does , asking time interval in which pariticles reaches to respective edges , or velocity of them , or something else .... "

In my views you should post this as a question ! I have answered to all these situation ... And In my views asking time interval will be more realistic situation..! You should try this .... and do post it as question , and I have answer to this question .. we can telly that ..! Also You asking time will be need good calculus ... you can check that at wolframalpha

For simplicity we can take data as Wo=1 rad/sec , a=1m (side) !

You meant Question to be a Note , right?
