 \\ \text{Given:} \\ \\ \Theta =50^{o}, \text{force},(A) = 200 \; N, \text{force},(B) = 300\; N \\ \text{Resultant force },(F_{net})=\sqrt{A^{2}+B^{2}+2AB \; \cos \Theta } \\ F_{net}=\sqrt{A^{2}+B^{2}+2AB \; \cos 50^{\circ}}

\Rightarrow \sqrt{(200)^{2}+(300)^{2}+2\times 200 \times300\times 0.62}

=455.12\; N
