Using Equation 3.1, calculate the period of your pendulum for a length of 160 cm or for the maximum length you used. How does this compare with your experimental value? Calculate the percent error. Use the calculated value of the period as the standard value
When L = 160cm, T = 2 54 . s. How well this compares to your experimental value
will depend on how carefully you did your work and the percent error will show that.
