The least speed required at the lowest point of a circular path for an object to complete the circle is √5gR.

1. Correct
2. Incorrect
3. Not enough information
4. Irrelevant

Correct answer: Correct

Solution

For a body to complete a vertical circular motion, the minimum velocity at the bottom is derived using energy conservation and the condition for tension at the top. This value is √5gR.
