Parallelogram law of forces states that if two forces acting simultaneously at a point be represented in magnitude and direction by two adjacent sides of parallelogram, their resultant may be represented in magnitude and direction by
1
longer side of the other two sides.
2
shorter side of the other two sides.
3
diagonal of the parallelogram which passes through their points of intersection.
4
diagonal of the parallelogram which does not pass through their point of intersection.
