Find the magnitude and direction of resultant of two vectors without using the parallelogram of vector addition.

Let be two vectors acting at angle . is the resultant of Therefore,   Let, the resultant make angle with . Also, Thus, for two vectors acting in the same direction, the magnitude of the resultant vector is equal to the sum of the magnitude of two vectors and acts along the direction of 153 Views
