A force table is used to determine the resultant of two forces acting in the same plane. The following forces are applied: - Force \(F_{1}\) = 5.0 N acting at \(30^{\circ}\) north of east. - Force \(F_{2}\) = 8.0 N acting at \(120^{\circ}\) measured anticlockwise from the east direction. Using the data, answer the questions below.

Question Parts

( a )
Resolve each force into its east‑west (x) and north‑south (y) components (in newtons, to three significant figures).
( b )
Using the components obtained in part (a), calculate the magnitude and direction (angle north of east) of the resultant force \(R\). Give the magnitude to three significant figures and the direction to one decimal place.
( c )
When the same forces are added graphically using the parallelogram method on the force table, a slightly different magnitude of \(9.2\) N is obtained. Discuss two reasons why the graphical result may differ from the analytical result of part (b) and suggest how the accuracy of the graphical method can be improved.
