A simple pendulum has a time period `T`. The pendulum is completely immersed in a non-viscous liquid whose density is one-tenth of that of the material of the bob. The time period of the pendulum immersed in liquid is

A simple pendulum has time period 3sec. The pendulum is completely immersed in a nonviscous liquid whose density is 1//10th of that of the material of the bob. Then time perod of that pendulum is

A simple pendulum oscillating in air has a time period of sqrt(3) s. Now the bob of the pendulum is completely immersed in a non-viscous liquid whose density is equal to (1)/(4) th that of the material of the bob. The new time period of simple pendulum will be

A metallic sphere is hung from a spiral spring and it executes vertical vibrations with a period T. The ball is now completely immersed into a non viscous liquid whose density is (1/20)th of that of the material of sphere. Then the time period of the vibrations of this sphere immersed in the liquid is
