Question
The time period of a bundle floating in water is T. How will the periodic period of the same vessel be affected while floating in salty plank?
✓

Answer

Oscillation period of a floating rectangular wooden plank.
$T =2 \pi \sqrt{\frac{h}{g}}$
We know that wooden plank will sink less in salty water. For this reason, the value of H will be less than before, here G is constant. For this reason the value of period T will be less than before.
