Question 2 NECO_MODEL_QUESTIONS_VOL1 • 2022 • PHYSICS • practical

A force table is set up to determine the resultant of two forces acting on a small ring. The following forces are applied using hanging masses and pulleys: - Force F₁: magnitude 5.0 N acting at 30° north of east. - Force F₂: magnitude 8.0 N acting at 120° measured anticlockwise from the positive x‑axis (east). The student is required to (i) resolve the forces analytically into their rectangular components, (ii) obtain the resultant analytically, (iii) verify the result by the graphical (parallelogram) method on the force table, and (iv) comment on any discrepancy between the two methods.

Question Parts

( a )
Resolve each force into its horizontal (x) and vertical (y) components. Show all work.
( b )
Obtain the resultant force components (Rₓ, Rᵧ) by algebraically adding the components of F₁ and F₂.
( c )
Calculate the magnitude and direction (θ_R measured north of east) of the resultant force.
( d )
The student also obtained a resultant of 9.4 N at 87° using the graphical (parallelogram) method on the force table. Discuss possible reasons for the small difference between the analytical and graphical results.
