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 V1 & V2. Let the vectors have the following orientation
parallelogram of these vectors is :
According to parallelogram law:
The process of determining the magnitude of a vector is known as vector resolution.
Magintude or resultant vector can be determined by using either sine law or cosine law.
