I am required to plot a graph of l(1+L^2/12l^2) on the x axis and T^2 on the y axis.The graph must be a straight line through the origin.I got the following values for the l values on the x axis .57,.47,.37,.27,.17 and corresponding values of T^2 2.46,2.52,2.56,3.24,8.12.As you can see my values are totally off and do not give the necessary slope needed to give 9.8 when subbed into the formula g=4pi^2/slope.Please advise on how i would go about changing the values to suit as i'm unable to do the experiment again(adsbygoogle = window.adsbygoogle || []).push({});

the original formula is T=2pi(sqr l/g) (1+L^2/12l^2)

Big L is 1.2m
