Question

when the bob us tight with a rod and this moving in vertical circle then derive the expression for velocity of lowest point Vmax and velocity at topmost point Vmin​

Answer 1

Answer: Velocity at lowest point in vertical circular motion

Explanation:

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. It will leave circular motion between M and H.
