Question 8

The magnitude of a force xi + 15j is N. Find the:
(a)   possible values of x;

(b)   directions of the forces, correct to the nearest degree
_____________________________________________________________________________________________________
Observation

Some of the candidates who attempted this question gave the values of x as 8 instead of ± 8, thus having only one value for x instead of 2. A number of them also lost the final mark as they left their answers as angles, i.e. 28° instead of bearing form or directions, i.e 28degrees.
