Question

A stone tied to a string when whirled in a vertical circular loop___

• A. angular acceleration provides required centripetal force
• B. instantaneous speed provides centripetal force
• C. tension in the string provides required centripetal force
• D. the weight of a stone provides the centripetal force

Answer 1

The correct option is C

tension in the string provides required centripetal force

When a stone tied to a string whirled in a vertical circular loop, tension in the string plays a very important role in keeping it in a constant circular loop by providing a centripetal or center seeking force as it is always directed towards the center of a circle.
