Satellite Energy & Weightlessness

A seconds pendulum is placed in a space laboratory orbiting round the earth at a height ' $3R$ ' from the earth's surface. The time period of the pendulum will be ( $R =$ radius of earth)

Show answer and solution

Answer: (d)

Inside an orbiting satellite everything is in free fall, so effective $g_{\text{eff}} = 0$ .
$T = 2\pi\sqrt{\frac{l}{g_{\text{eff}}}} \to \infty$ ; the pendulum does not oscillate.
So the answer is (d) infinite.
