Net force acting on ball upwards $=V\rho_w g-Vdg=V(\rho_w-d)g$

Hence acceleration of body upwards $a=\dfrac{V(\rho_w-d)g}{M}$

Speed of body on reaching the surface= $v=\sqrt{2ah}$

Hence the maximum height to which the ball jumps under action of gravity $=\dfrac{v^2}{2g}=\dfrac{2ah}{2g}=\dfrac{ah}{g} =\dfrac{V(\rho_w-d)h}{M}$
$=\dfrac{\dfrac{4}{3}\pi R^3.\rho_w-M}{M}h$

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
