- #12Can a pendulum clock be used in an earth-satellite?Ans : No. According to the relation:
`` T=2\pi \sqrt{\frac{l}{g}}``
The time period of the pendulum clock depends upon the acceleration due to gravity. As the earth-satellite is a free falling body and its geffective (effective acceleration due to gravity ) is zero at the satellite, the time period of the clock is infinite.
