Question

Obtain an expression for velocity of a body at lowest and highest point in case of vertical circle .? ​

Answer 1

If the velocity 'v' of the body is such that, v ≤ √2gr, then the body oscillates about point L, the lowest point of the vertical circle. If the velocity 'v' of the body is such that √2gr < v < √5gr , then the body leaves the circular path and acts like a projectile.
