Neco 2025 Physics Question 42
Practice objective / multiple choice question 42 from the 2025 Neco Physics examination.
In a pendulum experiment the period \(T\) is measured with a stopwatch that has a random error of \(\pm0.2\) s. The length \(L\) is measured with a meter rule that is calibrated 0.5 % too long (systematic error). The recorded values are \(T=2.00\) s and \(L=1.00\) m. Using \(g=\frac{4\pi^{2}L}{T^{2}}\), calculate the percentage uncertainty in the calculated value of \(g\) and state whether the random or systematic error contributes more to this uncertainty.
