Two blocks ( m = 0.5 kg and M = 4.5 kg) ...

Two blocks ( m = 0.5 kg and M = 4.5 kg) are arranged on a horizontal frictionless table as shown in figure. The coefficient of static friction between the two blocks is `(3)/( 7)`. Then the maximum horizontal force that can be applied on the larger block move together is `"_____________"` N. ( Round off to the Nearest Integer ) [Take as `9.8 ms^(-2)` ]
