Period of simple harmonic oscillators

You might need: Calculator


Astronauts transport a pendulum that has a period of 1s on Earth to another planet, Xircon-4. The pendulum has a 0.50kg mass attached to a massless cord of length LE. The gravitational field on Xircon-4, gx, is 10.8m/s2.
To give the pendulum a period of 1s on Xircon-4, by how much should the astronauts adjust the pendulum?
Write your answer to two significant figures.
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3/5
  • a simplified improper fraction, like 7/4
  • a mixed number, like 1 3/4
  • an exact decimal, like 0.75
  • a multiple of pi, like 12 pi or 2/3 pi
