Question

derivation of the law of parallelogram​

Answer 1

Explanation:

The law of parallelogram of forces states that if two vectors acting on a particle at the same time be represented in magnitude and direction by the two adjacent sides of a parallelogram drawn from a point their resultant vector is represented in magnitude and direction by the diagonal of the parallelogram drawn from .

Answer 2

Answer:

Let P and Q be two vectors acting simultaneously at a point and represented both in magnitude and direction by two adjacent sides OA and OD of a parallelogram OABD as assumed. Then, according to parallelogram law of vector addition, diagonal OB represents the resultant of P and Q.
