Question

As shown in the figure, a mass is performing vertical circular motion. The average velocity of the particle is increased, then at which point will the string break?\

Professor PC Thomas Classes · Answer

(b) : When a mass is moving in a vertical circle, it string experiences the maximum force when it is at the lowest point $B$. Therefore, tension at $B$ is maximum $$ =	ext { Weight }+\frac{m v^{2}}{R} $$ So, the string breaks at point $B$.\
