Problem 14.91 Experimenting with pendulums, you attach a light string to the ceiling and attach a small metal sphere to the lower end of the string. When you displace the sphere 2.00 m to the left, it nearly touches a vertical wall; with the string taut, you release the sphere from rest. The sphere swings back and forth as a simple pendulum, and you measure its period T. You repeat this act for strings of various lengths I, each time starting the motion with the sphere displaced 2.00 m to the left of the vertical position of the string. In each case the sphere's radius is very small compared with L. Your results are given in the table: Z (m) 12.00 10.00 8.00 6.00 5.00 4.00 3.00 2.50 2.30 T (6) 6.96 6.36 5.70 4.95 4.54 4.08 3.60 3.35 3.27 Part E Graph T3 versus L. for for the six smallest values of L.
