2 uniform discs of masses 4M and M and of respective radii R and R/2 are placed on rough horizontal surface.length of the rod connecting them is 2R.coefficient of friction between the groung and both the discs if u.A constant horizontal force F acts on the bigger disc.Then,(1) if F = Mg . and there is no slipping anywhere. find acceleration of center of mass of the smaller disc.(2) same case. find elongation of the rod(in terms of Y, A,Mg,R)(3) if u=2/root(15) , and const. force F acts . find maximum acceleration the bigger disc can have without slip.
