A stone tied to a string is rotated in a vertical circle. The minimum speed of the stone during a complete vertical circular motion

Options

  1. Ais independent of the mass of the stone
  2. Bis independent of the length of the string
  3. Cdecreases with increasing mass of the stone
  4. Ddecreases with increasing length of the string

Correct answer

A. is independent of the mass of the stone

Step-by-step solution

Minimum speed with which the string is rotating in a vertical circle, ( v )   =   gr i . e , the minimum speed of stone is independent of the mass of stone.
