Topic: parallelogram law of vectors

Parallelogram Law of Vectors  states that when the adjacent sides of a parallelogram represent the magnitude and direction of two vectors, the resultants of the two vectors is represented in magnitude and direction by the diagonal of the parallelogram drawn from the common point. See fig 1 above When two vectors are inclined to each other, the resultant cannot be obtained by either addition or subtraction of the two vectors but by using the above stated Parallelogram law of vectors. ...
