Question

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 (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:
(A) 2T√(1/10) (B) 2T√(1/14) (C) 4T√(1/15) (D) 4T√(1/14)
