Rotate The RING!

There is a ring of mass $M = 2 \text{ kg}$ and radius $r = 0.5 \text{ m}$ . A stick is giving a force of $2\text{ N}$ on the ring such that the ring moves with an acceleration of $0.3\text{ m/s}^2$ (Ground is Rough). How much is $P$ if the coefficient of friction between ring and stick is $\dfrac P{10}$ .
