Question

state paralleled law of vector addition and find the magnitude and direction of the resultant of two vectors P and Q inclined to each other at angle theta with each other. what happens when theta is 0 and theta is90​

Answer 1

Answer:

Let P and Q be two vectors acting simultaneously at a point and represented both in magnitude & 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 vectors. According to parallelogram law of vector addition, diagonal OB represents the resultant of P and Q.
