Vedclass · Answer

(a) $F \cdot F \cdot \cos 	heta =F \cdot F \cdot \sin 	heta 	ext { or } 	an 	heta=1 	ext { or } 	heta=45^{\circ}$
$\left| F _1+  F _2ight| =\sqrt{F^2+F^2+2 \cdot F \cdot F \cdot \cos 45^{\circ}} ~\ =(\sqrt{2+\sqrt{2}}) F$

If $F _1$ and $F _2$ are two vectors of equal magnitudes $F$ such that $\left| F _1 \cdot F _2\right|=\left| F _1 \times F _2\right|$, then $\left| F _1+ F _2\right|$ equals to
