sir in an horizantal surface one block of mass 5 kg is placed on another block of 6 kg which is in contact with horizantal surface.there is no friction between between 6 kg block and horizantal surface.but there is a friction between 5 and 6 kg block ,cofficent of friction is 0.8 the block of mass m hanging from string freely which is in connected 2 mass of 5 kg frm other side.the max value of m if both blocks move relative to each other

Dear jauneet

acceleration of lower block a1 = .8N/6

acceleration of upper block a2 =(T-.8N)/5

 where N =5g   and T =mg

in limiting case a1 =a2

                   .8N/6  = (mg-.8N)/5

                   4N/6 = mg - .8N

                   4N =6mg -4.8N

                  6mg = 8.8 N

                  6mg =8.8*5g

                  m =22/3 kg
