Can a pendulum clock be used in an earth-satellite?

उत्तर

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.
