Two blocks (\( m = 0.5 \, \text{kg} \) and \( M = 4.5 \, \text{kg} \)) are arranged on a horizontal frictionless table as shown in figure. The coefficient of static friction between the two blocks is \( \frac{3}{7} \). Then the maximum horizontal force that can be applied on the larger block so that the blocks move together is ______ \( \text{N} \). (Round off to the Nearest Integer) [Take \( g \) as \( 9.8 \, \text{m s}^{-2} \)]
