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
Column IColumn IIi.If μ1=μ2=0a.May accelerate towards rightii.If μ1=μ2≠0b.May accelerate towards leftiii.If μ1>μ2c.Does not accelerateiv.If μ1<μ2d.May or may not accelerate
