Question

what is parallelogram law of vector addition

Answer 1

Parallelogram Law of Vector Addition states that when two vectors are represented by two adjacent sides of a parallelogram by direction and magnitude then the resultant of these vectors is represented in magnitude and direction by the diagonal of theparallelogram starting from the same point

Answer 2

Hi,

Here is your answer,

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

Now, Consider two vectors A and B that lie in a plane. From a common point O, draw a vector OP equal and parallel to A and vector QR equal and parallel to B. The parallelogram OPQR the resultant vector is given by OQ.
