ANSWER:Solution 68P Step 1 of 6: The free body diagram for mass M 1 Here the x-axis is taken along the surface of the wedge, Four forces acts on the block of mass 1 , Tension =T along x-axis Weight W= M g1 Normal force will be equal to the component of weight, N= W cos Using W= M g 1 N= M g cos 1 Friction force, f = N k k Using N= M g cos, 1 fk= Mkg co1
