An equilateral triangle ABCformed 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 other along AC as shown. Neglecting frictional effects, the quantities that are conserved as the beads slide down, are:

1.	An equilateral triangle ABCformed 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 other along AC as shown. Neglecting frictional effects, the quantities that are conserved as the beads slide down, are:
Answer» ANGULAR velocity and total energy Total angular MOMENTUM and total energy Angular velocity and M.I. about the AXIS of rotation Total angular momentum and M.I. about the axis of rotation Answer :B
