Explanation of Solution
Given information:
Diagram:
The parallelogram law of vector addition states that if two vectors are acting simultaneously at a point, then it can be written both in magnitude and direction by their adjacent sides from a point and their sum is equal to the resultant vector represented in both direction and magnitude by the diagonal of the parallelogram passing through the point.
Consider the above figure:
The vectors
According to the above law, the side
Thus, it proves that the diagonal
