A loop of mass M with two identical ring...

A loop of mass M with two identical rings of mass `3/2 M` each at its top hangs from a ceiling by an inextensible string. If the rings gently pushed horizontally in opposite directions, find the angular distance covered by each ring when the tension in the string vanishes for once during their motion.
