Question

Mimimum velocity of object at lowest point of verticsl circle

Answer 1

It is maximum at the bottom-most position and minimum at the uppermost position of the vertical circle. ... If the velocity 'v' to the body is such that is v <= √2gr , then the body oscillates about point L, the lowest point of the vertical circle

Answer 2

Minimum velocity of object at lowest point of vertical circle is √gR.
