Q1Forces and EquilibriumFree sample

Fig. 1

Four horizontal forces act at a point $O$ and are in equilibrium. The magnitudes of the forces are $F$ N, $G$ N, $15$ N and $F$ N, and the forces act in directions as shown in the diagram.

(i)

Show that $F = 41.0$ , correct to 3 significant figures.

(ii)

Find the value of $G$ .
