density = mass / volume
volume = 4/3 * Pie* r^3
volume = 4/3*3.14*(2)^3 = 33.5 cm^3
density = 100 / 33.5 = 2.98 g / cm^3
Thanks & Regards,

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
