A force table is set up to investigate the resultant of two forces. The following data are recorded: - Force F₁: magnitude 5.0 N acting at 30° measured anticlockwise from the positive x‑axis. - Force F₂: magnitude 8.0 N acting at 120° measured anticlockwise from the positive x‑axis. - The experimental resultant obtained from the table’s spring scale is 9.6 N directed at 88° from the positive x‑axis. Using this information, answer the following:

Question Parts

( a )
Calculate the theoretical magnitude and direction of the resultant by resolving the two forces into components and then recombining them.
( b )
Find the percentage difference between the experimental magnitude (9.6 N) and the theoretical magnitude obtained in part (a).
( c )
State the horizontal (x) and vertical (y) components of the theoretical resultant.
( d )
Discuss two possible sources of error that could cause the experimental resultant to differ from the theoretical value and suggest a method to minimise each error.
