Three bodies A,B and C of masses 10g each are tied to a thread-pulley system as shown in the figure. Assume the masses of the pulley and the threads are negligible and there is no friction in the pulley. If the co-efficient of friction between the bodies A and B with the horizontal surface is 0.1, then the acceleration with which the body C comes down is
[Acceleration due to gravity =10ms−2 ]
