Question 2 WAEC_MODEL_QUESTIONS_VOL1 • 2017 • PHYSICS • practical

A force table is set up with two known forces acting on a ring: • Force F₁ = 5.0 N directed 30° above the positive x‑axis. • Force F₂ = 8.0 N directed 120° measured counter‑clockwise from the positive x‑axis. The student must determine the resultant of F₁ and F₂ and then find the magnitude and direction of a third force that will bring the system to equilibrium.

Question Parts

( a )

Resolve each force into its horizontal (x) and vertical (y) components.

( b )

Using the components, calculate the magnitude and direction (angle measured from the positive x‑axis) of the resultant force R of F₁ and F₂.

( c )

Determine the magnitude and direction of a third force F₃ that must be applied to bring the system to equilibrium. State its components as well.

( d )

Identify one probable source of systematic error in the force‑table experiment and suggest a method to reduce it.
