Problem
A student uses a stopwatch with a least count of 0.1s to time 50 complete oscillations of a stretched string. The recorded time for the 50 oscillations is 38.4s.
(i) Calculate the frequency of oscillation of the string.
(ii) Considering the possible timing error of ±0.1s in the measurement, determine the maximum possible percentage error in the calculated frequency.
(iii) Suggest any two practical steps the student can take to reduce the percentage error in such an experiment.
