A ring of mass `m` and radius `r` is projected with velocity `v_(0)` while spinning with angular velocity `(v_(0))/(4 r)` at the bottom of an inclined plane of angle of inclination `theta – 60^@` as shown in fig. The ring begins to roll without slipping after colliding with the inclined plane. Before collision sence of rotation is depicyed in the fig.
.
If the ring after collision rolling up the incline then maximum height attained by it is :
A. `(V_(0)^(2))/(2 g)`
B. `(V_(0)^(2))/(128 g)`
C. `(V_(0)^(2))/(64 g)`
D. `(V_(0)^(2))/(32 g)`.
