Radioactive decay is purely random event. It is independent of external factors that is the environment and also independent of the surface chemistry of the radioactive material. The only thing that can disturb half life of a radioactive material is when it interacts with a high energy particle. The half life is dependent upon the instability of the radioactive material which is completely unpredictable.

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
