Addition of vectors
Parallelogram law of vector addition
According to the parallelogram law of vector addition:
“If two vector quantities are represented by two adjacent sides or a parallelogram then the diagonal of parallelogram will be equal to the resultant of these two vectors.”
Consider two vectors and .
Let the vectors have the following orientation
parallelogram of these vectors is :
According to parallelogram law:
Magnitude Of resultant Vector
Magnitude of resultant vector can be determined by using either sine law or cosine law.
