    Can we use a pendulum watch in an artificial satellite?

    Answer:

                    No. In an artificial satellite, a body is in a state of weightlessness, i.e. \[~g=\text{ }0\]. \[\therefore \]  \[T=2\pi \sqrt{\frac{l}{g}}=\infty \] Inside the satellite, the pendulum does not oscillate. Hence a pendulum watch cannot be used in an artificial satellite.
