A boy is pushing a ring of mass 2 kg and radius 0.5 m with a stick as shown in the figure. The stick applies a force of 2 N on the ring and rolls it without slipping with an acceleration of . 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 . The value of is

From Eqs. (i) and (ii),
From Eq. (ii),
Note: But if only normal reaction applied by the rod is considered to be 2 N
