Question

When a ball is whirling is a circle and the string supporting it suddenly break up, then the

• A. ball stops
• B. ball flies away tangentially
• C. ball falls towards the center
• D. None of the above

Answer 1

The correct option is B

ball flies away tangentially

Centripetal and centrifugal forces:

1. When the ball is tied to a string, it has centripetal and centrifugal forces along the radial direction of motion, so when the rope breaks, there is no force in the radial direction, and the ball flies off tangentially due to inertia.
2. Therefore, When a ball is whirling is a circle and the string supporting it suddenly break up, then the ball flies away tangentially

Hence, option (b) is correct answer.
