A beaker containing a liquid with a reflecting surface is placed on a turntable and set to rotate about its axis as shown in the figure. The angle made by the reflecting surface with the horizontal is given by ( )= ^2 x g The radius of curvature of the surface R x . Then

Options

  1. Ay is proportional to x^4 .
  2. By is proportional to x^2 .
  3. CThe focal length of the reflecting surface is g / 2 ^2 .
  4. DIf the angular speed of rotation is 2 rad . s ⁻¹ then the radius of curvature of the mirror is 2.5 m .

Correct answer

D. If the angular speed of rotation is 2 rad . s ⁻¹ then the radius of curvature of the mirror is 2.5 m .
