A seconds pendulum is placed in a space laboratory orbiting round the earth at a height ' $3 R$ ' from the earth's surface. The time period of the pendulum will be $(\mathrm{R}=$ radius of earth $)$
zero
$\frac{2}{3}$s
4 s
infinite
Solution
In auter space, $\mathrm{g}=0$. Therefore, $\mathrm{T}=\infty$.
