Question

A uniform U-tube contains a liquid column of total length 2 m. The liquid is displaced slightly and released. Neglect viscosity and take g = 10 m/s². If ω² = N s⁻², find N.

G1 Physics · Accepted Answer

For a U-tube, ω² = 2g/L. With g = 10 m/s², L = 2 m, ω² = 20/2 = 10 s⁻². Hence, N = 10.
