A string of length ' $L$ ' fixed at one end carries a body of mass ' $m$ ' at the other end. The mass is revolved in a circle in the horizontal plane about a vertical axis passing through the fixed end of the string. The string makes angle ' $\theta$ ' with the vertical. The angular frequency of the body is ' $\omega$ '. The tension in the string is

Show answer and solution

Answer: (b)

Radius of the circle $r = L\sin\theta$ .
$T\sin\theta = m\omega^2 L\sin\theta$
$T = mL\omega^2$
So the answer is (b).
