Given below the arrangement of loading on the larger boat by two tug boats.

F₁ = 5 N

F₂ = 4 N

Angle between them θ = 90⁰

Resultant between two vectors, [tex]F=\sqrt{F_1^2+F_2^2+2F_1F_2cos\theta }[/tex]

Substituting

   [tex]F = \sqrt{5^2+4^2+2*5*4*cos 90} \\ \\ = 6.403 N[/tex]

So magnitude of the net force on the block = 6.403 N
