State parallelogram law of vectors addition .Find analytcallly the magnitude and direction of resultant vector, When (i) two vectors are parallel to each other (ii) two vectors are perpendicular to each other.

Text Solution

Verified by Experts

If two vectors are represented in magnitude and direction by two sides of the parallelogram drawn from the same point, then the resultant is represented in magnitude and direction by the diagonaol of the parallelogram drawn from the same point .
