Neco 2021 Physics Question 43
Practice objective / multiple choice question 43 from the 2021 Neco Physics examination.
A simple pendulum of length \(0.50\ \text{m}\) is used to determine the acceleration due to gravity. Five measurements of the period give \(1.42\ \text{s},\ 1.44\ \text{s},\ 1.43\ \text{s},\ 1.41\ \text{s}\) and \(1.45\ \text{s}\).\n(i) Calculate the experimental value of \(g\) from the average period.\n(ii) Identify two possible systematic errors in this experiment and suggest one practical precaution for each to reduce the error.\n(iii) Assuming the swing amplitude is \(5^{\circ}\) and air resistance increases the period by \(0.2\%\), calculate the corrected value of \(g\) (give your answer to two decimal places).
