A simple pendulum and a mass-spring system each have a time period TTT on Earth. They are transported to a high-gravity exoplanet where the acceleration due to gravity is 4g4g4g, where ggg is the acceleration due to gravity on Earth. What are the time periods of the pendulum and the mass-spring system on this exoplanet?
Simple pendulum: 2T2T2T, Mass-spring system: TTT
Simple pendulum: 0.5T0.5T0.5T, Mass-spring system: TTT
Simple pendulum: 0.5T0.5T0.5T, Mass-spring system: 0.5T0.5T0.5T
Simple pendulum: TTT, Mass-spring system: 0.5T0.5T0.5T
