MHT CET Physics question
A rectangular block of mass 'm' and cross-sectional area 'A' floats on a liquid of density . If it is given a small vertical displacement from equilibrium, it starts oscillating with frequency 'n' equal to (g = acceleration due to gravity) [MHT-CET 2023]
Answer: (B)
Solution
The restoring force per unit displacement (extra buoyancy) is , so \dfrac{1}{2π}$ =
