A student is required to determine the acceleration due to gravity (g) using a simple pendulum.

Question Parts

( a )
State a step‑by‑step procedure for measuring the length of the pendulum and the period of oscillation. Mention at least two precautions that should be observed.
( b )
The length measured is L = 0.540 m (three significant figures). Five successive timings for 20 complete oscillations are: 28.62 s, 28.55 s, 28.68 s, 28.60 s, 28.57 s. Calculate (i) the mean period of one oscillation and (ii) the standard deviation of the period.
( c )
Using the mean period obtained, calculate the experimental value of g. Show the rearranged formula and give g to two decimal places.
( d )
Determine the percentage error in the experimental value of g, taking the accepted value as 9.81 m s⁻². Comment on two possible sources of error based on the procedure.
