Question: Three coplanar forces each equal to P, act at a point. The middle one makes an angle of ${{60}^{o}}$with each one of the remaining two forces. If by applying force Q at that point in a direction opposite to that of the middle force, equilibrium is achieved, then


1) $P=Q$
2) $P=2Q$
3) $2P=Q$
4) None of these
Solution: Explanation: No Explanation
