If a simple pendulum is arranged in an artificial satellite its    a) Time period becomes infinity        b) Frequency becomes infinity         c) Both time period and frequency become infinity        d) It does not oscillate

When the bob of a simple pendulum is displaced from its equilibrium position and released, It will oscillate if the restoring force ie. is not zero. In artificial satellite effective g = 0. So the pendulum does not oscillate.Again . If g = 0, So option - (1) is correct.
