A block of mass m

_{2}is placed on a horizontal table and another block of mass m_{1}is placed on top of it. An increasing horizontal force F = at is exerted on the upper block but the lower block never moves as a result. If the coefficient of friction between the blocks is $$\mu$$_{1}and that between the lower block and the table is $$\mu$$_{2}, then what is the maximum possible value of $$\mu$$_{1}/ $$\mu$$_{2}?4
