A bob is whirled in a horizontal plane by means of a string with an initial speed of $\omega \mathrm{rpm}$. The tension in the string is $T$. If speed becomes $2 \omega$ while keeping the same radius, the tension in the string becomes:
  • $4 T$
  • B
    $\frac{T}{4}$
  • C
    $\sqrt{2} T$
  • D
    $T$

Answer: A.
