As shown in the figure, two strings of length $l$ each are attached with a vertical axis $AB$ of length $l$. Strings are $AC$ and $BC$. At point $C$ a point mass m is attached. Mass rotates about axis with angular velocity. Tensions in $AB$ and $BC$ are $T_1$ and $T_2$ respectively. Choose the $CORRECT$ alternative :-
  • A$T_1 = T_2$
  • Bstring $AC$ will remain taut only if $\omega \geq \sqrt{2g/l}$
  • Cstring $BC$ will remain taut for any value of $\omega$.
  • D$T_1 -T_2 = 2mg$
