In case of vertical circular motion of a particle by a thread of length $\displaystyle r$ if the tension in the thread is zero at an angle $\displaystyle 30$° shown in figure, the velocity at the bottom point $\displaystyle (A)$ of the circular path is
( $\displaystyle g=$ gravitational acceleration)
Official answer
From NTA’s final answer key for this paper.
(4)
$\displaystyle \sqrt{\frac{7}{2} g r}$
