The net force acting on the body is given as,


F_(net)=\lvert F_1+F_2\rvert

For the first diagram:

The net force is given as,


\begin{gathered} F_(net)=\lvert(11\text{ N})+(-71\text{ N})\rvert \\ =60\text{ N} \end{gathered}

For the second diagram:

The net force is given as,


\begin{gathered} F_(net)=\lvert(405\text{ N})-(403\text{ N})\rvert \\ =2\text{ N} \end{gathered}

For the third diagram:

The net force is given as,


\begin{gathered} F_(net)=\lvert(227\text{ N})-(190\text{ N})\rvert \\ =37\text{ N} \end{gathered}

For the fourth diagram:

The net force is given as,


\begin{gathered} F_(net)=\lvert(22.7\text{ N})-(15.3\text{ N})\rvert \\ =7.4\text{N} \end{gathered}

On comparing different values of the net force on the different systems, it is found that the net force is maximum in the first diagram.
