2.4 C4: DETERMINATION OF HEIGHT, H OF THE CEILING USING A SIMPLE PENDUL Procedure. Suspend a pendulum bob from the ceiling by a long thread as it nearly touches the
as shown in Figure 4.1. Starting the pendulum bob at about h = Sem from the ground, use a sto
to determine the time t for ten (10) oscillations Repeat with h = 10, 15, 30, 35, 40, 45 and 50om.

1. Transform the formula T = 271 into a linear form and plot a suitable graph.
2. Determine the slope of the graph
3. Determine the intercept on the h-axis
4. Determine the value of g from the graph
5. Determine the value of H from the graph
6. Estimate the error ing.​
