Practical – Finding the value of gravity

1. We had to set up an experiment that looked like the attached diagram. By adding different masses (independent variable) we would measure angle theta (dependent variable). Our task was to draw an appropriate graph and from the gradient, see what our gravity value came to.

So far i have had no luck and what I am stuck on is the variables being plotted on the graph, as my first graph attempt didn’t produce a value close to 9.81m/s^2 or 10N/kg. All I’m asking is if I can have a bit of direction with the variables I am supposed to display on my graph to find the correct value of gravity.
