A small mass m is attached to a string of length L to make a simple pendulum that swings with period T. Suppose the mass is cut in half, what might the new period of oscillation be? Α. 2T T В. С.Т D. V2T An alien on Pluto has the exact same pendulum. What is the period of oscillation of the alien's pendulum in terms of T, given that the acceleration due to gravity on Pluto is 1/16 of the acceleration due to gravity on Earth? TPluto
