Three forces, P, Q and R, of magnitudes 500 N, 200 N and 300 N respectively, act on
a point O in the directions shown in the diagram below.
The forces are NOT drawn to scale.

2.1 Refer to the information in the diagram above and give a reason why forces
P, Q and R are classified as vectors. (2)
2.2 Determine the magnitude and direction of the resultant force, either by
CALCULATION or by ACCURATE CONSTRUCTION AND MEASUREMENT.
(Use scale 10 mm = 50 N.) (8)
