7. You have carried out an experiment to investigate the effect of the length of a pendulum on the time period of oscillation. Theory says that the pendulum should follow the rule T = 2n Where T is the time period (seconds) Lis the length of the pendulum (metre) G is the acceleration due to gravity (g = 9.81 m/s²) Calculate the expected percentage error in the time period calculation if your measurement of length is X% high. %3D Values in table at the end
