How to find resultant of two vectors?

Answer 1

Vectors

1. A vector is a physical quantity that has both magnitudes and directions.
2. Acceleration, velocity, and displacement are examples of vectors.

To find the resultant of two vectors

If two vectors $\overrightarrow{P}$ and $\overrightarrow{Q}$ directed along OA and OB, then the resultant of two vectors $\overrightarrow{R}$$=\overrightarrow{P}+\overrightarrow{Q}$ will be towards the diagonal OC.

The magnitude of the resultant vector is defined by the form $R=\sqrt{\left(P^2+Q^2+2PQ\cos \theta \right)}$, where $\theta$ is the angle between two vectors.

The diagrammatic representation of the vectors and the resultant is,
