Proceed as follows;
i)Adjust the length Lof the pendulum to 1meter.
ii)Displace the bob side ways to an angle of about 45o (estimate) and let the pendulum switching for 10 oscillations and record the time, t, take for the ten oscillations.
iii)Repeat the same for other values of L as shown in the table below and fill in the columns of the table as indicated. (8mks)
iv)Plot a graph of T2 against L.

v)Determine the gradient
