4. An equilateral triangle ABC formed from a uniform wire has two small identical beads initially located at A. The triangle is set rotating about the vertical axis AO. Then the beads are released from rest simultaneously and allowed to slide down; One along AB and the other along AC as shown. Neglecting frictional effects, the quantities that are conserved as beads slides down are
answer is - angular momentum and total energy conserved
as the beads are sliding ,distance from axis of rotation is changing so moment of inertia is changing ...
now since there is no non conservative force such as friction so total energy must be conserved ...
no external torque acts on the system so its angular momentam must be conserved ....
W -> changes , I-> changes , L->constant , E->constant
option b is correct
