A simple pendulum oscillating in air has period T. The bob of the pendulum is completely immersed in a non-viscous liquid. The density of the liquid is $\displaystyle \frac{1}{16}$ th of the material of the bob. If the bob is inside liquid all the time, its period of oscillation in this liquid is :
Official answer
(2)
$\displaystyle 4 \mathrm{~T} \sqrt{\frac{1}{15}}$
