Q: A thin uniform metallic rod of mass M and length L is rotated with a angular velocity ω in a horizontal plane about a vertical axis passing through one of its ends. The tension in the middle of the rod is

(a) $ \displaystyle \frac{1}{2} M L \omega^2 $

(b) $ \displaystyle \frac{1}{4} M L \omega^2 $

(c) $ \displaystyle \frac{1}{8} M L \omega^2 $

(d) $ \displaystyle \frac{3}{8} M L \omega^2 $

Ans: (d)
