Dear Amrit pal
at the given instant total energy of ring is E = 1/2 I w2 + 1/2 mv2
=1/2 I (V/R)2 + 1/2 mV2
here I =1/2 m (R2 -r2)
E = 1/4 m[1-(r/R)2]V2 + 1/2 mV2
let the ring move L distance in the plane
increse in potential energy = mgLsin36.9
so from energy balance
1/4 m[1-(r/R)2]V2 + 1/2 mV2 = mgLsin36.9
find L from these equation
so total distance move by ring =L+2
