Question 2 NECO_MODEL_QUESTIONS_VOL1 • 2020 • PHYSICS • practical

A force table is used to verify the condition of equilibrium for a particle at the centre of a ring. Three forces act on the ring: - Force F₁: magnitude 5 N, direction 0° (along the positive x‑axis). - Force F₂: magnitude 4 N, direction 60° measured counter‑clockwise from the positive x‑axis. - Force F₃: unknown magnitude, direction to be determined, acting so that the particle remains at rest. Answer the following questions:

Question Parts

( a )

Resolve forces F₁ and F₂ into their horizontal (x) and vertical (y) components and obtain the resultant components of the two known forces.

( b )

Using the equilibrium condition (net force zero), calculate the magnitude of the required third force F₃ and state its direction measured counter‑clockwise from the positive x‑axis (give the angle to one decimal place).

( c )

If the student measures the magnitude of F₃ as 6.0 N, compute the percentage error in the measured value.

( d )

List any two possible sources of error that could affect the accuracy of the experiment.
