The Correct Option is B
Solution and Explanation
When a sphere is rotating in a vertical circle,
it exerts the maximum outward pull when it is at the lowest point B.
Therefore, tension at B is maximum = Weight $+\frac{mv^2}{R}$
So, the string breaks at point B.
it exerts the maximum outward pull when it is at the lowest point B.
Therefore, tension at B is maximum = Weight $+\frac{mv^2}{R}$
So, the string breaks at point B.
