A beaker of radius r is filled with water refractive index up to a height H as shown in the fi on the left The beaker is kept on a horizontal table rotating with angular speed w This makes water surface curved so that the difference in the height of water level at the center and at circumference of the beaker is h h H h r as shown in the figure on the right Take surface to be approximately spherical with a radius of curvature R Which of the following is correct g is the acceleration due to gravity A R B R h r 2h 3r 2h H A 3H C Apparent depth of the bottom of the beaker is close to 3 1 H D Apparent depth of the bottom of the beaker is close to 3 1 H 4g h
