The stick applies a force of 2 N on the ring and rolls it without slipping with an acceleration of 0.3 m/s 2 .The coefficient of friction between the ground and the ring is large enough that rolling always occurs and the coefficient of friction between the stick and the ring is 10 P. The value of P is :
