A boy is pushing a ring of mass 2kg and radius 0.5 m with a Stick the stick applies a Force of 2N on the ring and rolls it without slipping with accl of 0.3,/s^2 the coeffcient of friction b/w the ground and ring is large enough that rolling always occurs and coefficient of friction b/w stick and ring is(p/10) find p?
