A pendulum with a bob of mass 0.40 kg is pulled back and released from an angle of 10° to the vertical. The period of the pendulum on Earth is 1.55 s. This same pendulum is taken to another planet, where its period is 1.00 s. The acceleration due to gravity g on the second planet is most nearly:
A) 4.08 m/s²
B) 11.8 m/s²
C) 19.6 m/s²
D) 23.5 m/s²
