its 5am here, theres no way i can read all that and understand it... can you give me an explanation which is more comprehensible?

use the conservation of angular momentum about the centre point... |dw:1338801480957:dw| find ratio of angular velocities using law of grativation and equate them with the ratio of moment of inertia (using the above equation)..this should work.if u get struck then tell me..
