Question

derive expression for magnitude and direction of resultant vector in above law​

Answer 1

Answer:

Let P and Q be two vectors acting simultaneously at a point and represented both in magnitude and direction by two adjacent sides OA and OD of a parallelogram OABD as shown in figure. Let θ be the angle between P and Q and R be the resultant vector.
