1.	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 t0 in air. Neglecting frictional force of water and given that the density of the bob is (43)1000kg/m3. What relationship between t and t0 is true?
Answer» 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 $(\frac{4}{3}) 1000 k g / m^{3}$ . What relationship between $t$ and $t_{0}$ is true?
