1. The problem statement, all variables and given/known data A ring of mass 100gm connecting freely two identical thin loops of mass 200gm each, starts sliding down from point A at t=0. The centres of loops are B and C.The loops move apart over a sufficciently rough horizontal surface.[Neglect the friction between the ring and the hoop]g=10 Find i) The normal reaction acting on each loop given by the horizontal surface at t=0 ii)Acceleration of loop at t=0 Given angle ABC=ACB=45 2. Relevant equations I had no idea of it...What to use? 3. The attempt at a solution I tried to balance the forces acting at point A. but get nothing ..Thanks for help.
