Physics - SHM Question with Solution | TestHub

$\text{T}=2\pi \sqrt{\frac{\text{L}}{\text{g}}}$

Where L is the length of the liquid is one of the limbs. However, if L is taken to be the length of the liquid column, then the length of liquid in each limb is$\frac{\text{L}}{2}$.

$\Rightarrow \text{T}=2\pi \sqrt{\frac{\text{L}}{2\text{g}}}$

$\Rightarrow \text{M}=\left(\text{AL}\right)\text{d} \Rightarrow \text{L}=\frac{\text{M}}{\text{Ad}}$

$\Rightarrow \text{T}=2\pi \sqrt{\frac{\text{M}}{2\text{Adg}}}$
