For the figure, both the pulleys are massless and frictionless. The right side pully can move. A force F, of any possible magnitude, is applied in horizontal direction. There is no friction between M and ground.
μ1 and μ2 are the coefficients of friction between the blocks as shown. Column I gives the different relations between μ1 and μ2, and Column II is regarding the motion of M. Match the columns
