It is suggested that T and l are related by the equation
T = 2π
l
g
where g is the acceleration of free fall.
(a) A graph is plotted of T 2 on the y-axis against l on the x-axis. Express the gradient in
terms of g.
gradient = ................................................. [1]
(b) Values of l and t are given in Fig. 2.2.
l / cm t / s
90.0 18.9 ± 0.1
80.0 17.9 ± 0.1
70.0 16.7 ± 0.1
60.0 15.5 ± 0.1
50.0 14.1 ± 0.1
40.0 12.6 ± 0.1
Fig. 2.2
Calculate and record values of T and T 2 in Fig. 2.2. Include the absolute uncertainties in T 2.
