66What about the friction between the lowermost wedge and the ground?
ther are n wedges which are placed as shown in figure
coefficient of friction is \mu for each surface and masses of wedges are m,m/2,m/4...m/2^(n-1) respectively and after placing on one another they make \theta angle with each other.Now the system is released find the acceleration of top most wedge whose mass is m/2^(n-1)

1friction exists between lower block and ground and also coefficient of friction is \mu.
