A hollow spherical ball of radius 20 cm floats in still water, with half of its volume
submerged. Taking the density of water as 1000 kg/m3, and the acceleration due to
gravity as 10 m/s2, the natural frequency of small oscillations of the ball, normal to the
water surface is _________ radians/s (roundoff to 2 decimal places).
Explanation
Correct : 8.60-8.70
