The rod is released from rest in horizontal position. Then which of the following option(s) is/are correct?
(1) The speed of mass \( B \) at the instant rod becomes vertical is \( \sqrt{\frac{6}{5}} g l \).
(2) The tension in thread \( A B \) is \( \frac{18}{5} m g \), when the rod becomes vertical.
(3) The tension in thread \( B C \) is \( \frac{28}{5} m g \) when the rod becomes vertical.
(4) The hinge reaction at the hinge point \( C \) is \( \frac{28}{5} m g \) when the rod becomes vertical.
