As shown in the figure at point 
a mass is performing vertical circular motion. The average velocity of the particle is increased, then at which point will the string break?
A
B
C
D
D
Text Solution
Verified by ExpertsThe correct answer is:
B
When a sphere is rotating in a vertical circle, it exerts the maximum outward pull when it is at the lowest point 
Therefore, tension at 
is maximum 
Weight 
So, the string breaks at point
