A block of mass m2 is placed on a horizontal table and another block of mass m1 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 ?
