A simple pendulum and a mass hanging on a spring both have a period of 1 s when set into small oscillatory motion on Earth. They are taken to Planet X, which has the same diameter as Earth but twice the mass. Which of the following statements is true about the periods of the two objects on Planet X compared to their periods on Earth?

• Both are shorter

• Both are longer

• Both are unaffected

• The period of the mass on the spring is shorter, the pendulum is the same.

• The period of the pendulum is shorter, the mass on the spring is the same.
