A particle rotates in a horizontal circle of radius ' R ' in a conical funnel with constant speed ' V '. The inner surface of the funnel is smooth. The height of the plane of the circle from the vertex of the funnel is (g-acceleration due to gravity)

Options

  1. AV g
  2. BV 2 ~g
  3. CV ^2 2 ~g
  4. DV ^2 ~g

Correct answer

D. V ^2 ~g

Step-by-step solution

array ll & From figure, & N =m g & N = m V^2 R & = R g V^2 & R h = R g V^2 & h= V^2 g array
