A mass-spring system and a simple pendulum have identical periods of oscillation TTT on the surface of the Earth.
Both are taken to planet Y where the acceleration due to gravity is 4g4g4g (where ggg is the acceleration due to gravity on Earth).
What are the periods of the mass-spring system and the simple pendulum on Y?
Period of mass-spring system: TTT; Period of simple pendulum: T2\frac{T}{2}2T
Period of mass-spring system: T2\frac{T}{2}2T; Period of simple pendulum: TTT
Period of mass-spring system: TTT; Period of simple pendulum: 2T2T2T
Period of mass-spring system: 2T2T2T; Period of simple pendulum: T2\frac{T}{2}2T
