ADDITION OF VECTORS4
PARALLELOGRAM LAW OF VECTOR ADDITION
| ||
| Acccording 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." | ||
EXPLANATION
| ||
Consider two vectors  . Let the vectors have the following orientation | ||
 | ||
| parallelogram of these vectors is : | ||
 | ||
| According to parallelogram law: | ||
 | ||
MAGNITUDE OF
RESULTANT VECTOR | ||
| Magintude or resultant vector can be determined by using either sine law or cosine law. | ||
