Explanation:

Parallelogram Law of Forces

It states that if two forces acting at a point are represented in magnitude and direction by the adjacent sides of a parallelogram, then the diagonal of the parallelogram represents their resultant force.

Additional InformationKey points of Parallelogram Law of Forces

  • Two Forces: The law applies to two forces acting on a body.

  • Parallelogram Formation: These forces form adjacent sides of a parallelogram.

  • Resultant Force: The diagonal of the parallelogram represents the magnitude and direction of the resultant force.

  • Magnitude and Direction: The magnitude of the resultant force is found by using vector addition (geometrically represented by the diagonal), and its direction is the direction of the diagonal of the parallelogram.
