Three forces \( \overrightarrow{\mathrm{F}}_{1}, \quad \overrightarrow{\mathrm{F}}_{2} \) and \( \overrightarrow{\mathrm{F}}_{3} \) act on a particle as
\( \mathrm{P} \)
shown in the figure. Where \( \left|\vec{F}_{1}\right|=5 \mathrm{~N},\left|\vec{F}_{2}\right|=10 \mathrm{~N} \) and \( \left|\overrightarrow{\mathrm{F}}_{3}\right|=20 \mathrm{~N} \).
(A) \( 5 \mathrm{~N} \)
(B) \( -5 \mathrm{~N} \)
(C) \( 5 \sqrt{3} \mathrm{~N} \)
(D) \( -5 \sqrt{3} \mathrm{~N} \)
