Difficult$A$ rigid massless rod of length $3l$ has two masses attached at each end as shown in the figure. The rod is pivoted at point $P$ on the horizontal axis (see figure). When released from the initial horizontal position,its instantaneous angular acceleration will be
- A$\frac{g}{13l}$
- B$\frac{g}{3l}$
- C$\frac{g}{2l}$
- D$\frac{7g}{3l}$
