1. The problem statement, all variables and given/known data 2 Blocks connected by a string is placed on a rough horizontal floor,the coefficient of friction for block 1 is 0.2 while for block 2,it is 0.1. A force of 8N is applied on block 1 and a force of 1N is applied on block 2.Find the tension in the string and the frictional forces. See figure. 2. Relevant equations newton's law friction normal equation 3. The attempt at a solution I have the solution and it says there will be limiting friction case in block 1 since the net force acts in it's direction and there is a tendency of motion towards 8N force ,but I don't understand this if there is a tendency of movement then won't both frictional force and tension act simultaneously,so how can we say friction force will be maximum.
