SUMMARY
A person scuffing her feet on a wool rug accumulates a net charge of -73 µC, resulting in approximately 4.5 x 1014 excess electrons. To determine the increase in mass due to these electrons, the rest mass of an electron, which is approximately 9.11 x 10-31 kg, is used. Multiplying the number of excess electrons by the rest mass yields a mass increase of approximately 4.1 x 10-16 kg. This calculation illustrates the relationship between charge accumulation and mass increase due to electron gain.
