A simple pendulum with a solid metal bob has time period T. The metal bob is now completely immersed in a liquid of density one-tenth that of the bob. The liquid is non-viscous. Now the period of the same pendulum, remaining all the time immersed in the liquid, will be,
Why this question? If the combined gravitational force and buoyant force acting on the submerged mass is mg' then, g′=g[1−ρlρs] Where ρs is the density of solid bob and ρl is the density of the liquid. |
