$A$ 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 an angle $\theta$ with the vertical. The angular frequency of the body is $\omega$. The tension in the string is

• A
  $mL^2 \omega$
• B
  $mL \omega^2$
• C
  $\frac{\omega^2}{mL}$
• D
  $\frac{m \omega^2}{L}$
