The acceleration due to gravity at height \( \mathrm{R} \) above
\( \mathrm{P} \) the surface of the earth is \( g / 4 \). The periodic time of a
W simple pendulum in an artificial satellite at this height will be:
(1) \( \mathrm{T}=2 \pi \sqrt{2 l / g} \)
(2) \( \mathrm{T}=2 \pi \sqrt{l / 2 g} \)
(3) Zero
(4) Infinity
