Question

i) What is the difference tension in the string at the lowest point and highest point in
vertical circular motion.​

Answer 1

Explanation:

This is an expression for the velocity of a particle at any point performing a circular motion in a vertical circle. This is the expression for the tension in the string. Thus the tension in the string at the lowest point L is greater than the tension at the highest point H by six times the weight of the body

Answer 2

Answer:

Thus the tension in the string is maximum. At the topmost point, the centrifugal force acts vertically upward and the weight of the body acts vertically downward. Thus the tension in the string is minimum. Ans: Maximum tension at the bottom-most point is 110.4 N, Minimum tension at the topmost point is 51.6 N.
