AIPMT 2006

MCQ (Single Correct Answer)

-1

A uniform rod AB of length $$l$$ and mass m is free to rotate about point A. The rod is released from rest in the horizontal position. Given that the moment of inertia of the rod about A is ml²/3, the initial angular acceleration of the rod will be

$${{mgl} \over 2}$$

$${3 \over 2}gl$$

$${{3g} \over {2l}}$$

$${{2g} \over {3l}}$$
