Observer A sees a pendulum oscillating back and forth in a relativistic rocket and measures its period to be T_A.Observer B moves along with the rocket and measures the period of the pendulum to be T_B.What is true about these two time measurements? A)T_A T_B B)T_A = T_B C)T_A

Question

Observer A sees a pendulum oscillating back and forth in a relativistic rocket and measures its period to be T_A.Observer B moves along with the rocket and measures the period of the pendulum to be T_B.What is true about these two time measurements? A)T_A > T_B B)T_A = T_B C)T_A < T_B D)T_A could be greater or smaller than T_B depending on the direction of the motion.
