In space of horizontal \( \mathrm{EF}(\mathrm{E}=(\mathrm{mg}) / \mathrm{q}) \) exist as shown in figure and a mass \( m \) attached at the end of a light rod. If mass \( m \) is released from the position shown in figure find the angular velocity of the rod when it passes through the bottom most position
P
(A) \( \sqrt{\frac{\mathrm{g}}{l}} \)
(B) \( \sqrt{\frac{2 g}{l}} \)
(C) \( \sqrt{\frac{3 g}{l}} \)
(D) \( \sqrt{\frac{5 g}{l}} \)
