Block A of mass 35 kg is resting on a frictionless floor.

A steel block of 10 kg rests on a horizontal floor as shown. When three iron cylinders are placed on it as shown, the block and cylinders go down with an acceleration 0.2 m//s^(2) . The normal reaction R' by the floor if mass of the iron cylinders are equal and of 20 kg each, is ______ N. [Take g = 10 m//s^(2) and mu _(s) = 0.2 ]
