— Examiner report, October/November 2023, 5129/22 Q4(a)(i) (Cambridge)
This resultant force calculation is new to the syllabus and many candidates were unfamiliar with it. A common error was to multiply the two opposing forces together rather than subtract them.
— Examiner report, October/November 2023, 5129/22 Q4(a)(ii) (Cambridge)
Some candidates were able to describe how apparatus B could be used in the investigation. Many described how the weights could be attached to the spring balance. The most common incorrect response was candidates stating that this could measure the weight or the force exerted.
