The bob of a simple pendulum executes simple harmonic motion in water with a period

t,

while the period of oscillation of the bob is

{t_0}

in air. Neglecting frictional force of water and given that the density of the bob is

\left( {4/3} \right) \times 1000\,\,kg/{m^3}.

What relationship between

t

and

{t_0}

is true
