One end of a uniform rigid rod OA of length L and mass m is attached to a frictionless hinge at O. The other end of the rod is connected to the roof at B with a mass-less inextensible thread AB. Initially the rod is horizontal and at rest. The gravity is acting vertically downward as shown. Immediately after the thread AB is cut, the reaction on the rod at O is

- B. ଶ in the negative y-direction
- C. ଷ ସ in the negative y-direction
- D. 𝑚𝑔 in the positive y-direction
Answer: A. ସ in the positive y-direction
