Answer on Question #51281 – Physics - Mechanics | Kinematics | Dynamics

If two vectors are represented by two adjacent sides of a parallelogram the resultant is represented in ______ and ______.

triangle and rectangle

magnitude and direction

parallel and perpendicular

scalar and vector

Solution:

If two vectors, acting simultaneously at a point, can be represented both in magnitude and direction by the two adjacent sides of a parallelogram drawn from a point, then the resultant is represented completely, both in **magnitude** and **direction** by the diagonal of the parallelogram passing through the point.

(a)

(b)

$$\vec {P} + \vec {Q} = \vec {R}$$

Answer: magnitude and direction
