Pendulum \( \mathrm{A} \) is a physical pendulum made from a thin rigid and uniform rod whose length is \( \ell \).
\( P \)
One end of this rod is attached to the ceiling
W by a frictionless hinge so that rod is free to swing back and forth. Pendulum B is a simple pendulum whose length is also \( \ell \). The ratio \( \frac{T_{A}}{T_{B}} \) for small angular oscillations-
(1) \( \sqrt{\frac{3}{2}} \)
(2) \( \sqrt{\frac{2}{3}} \)
(3) \( \frac{2}{3} \)
(4) \( \frac{3}{2} \)
