SUMMARY

The discussion focuses on calculating the number of excess electrons acquired by a body with a static charge of -18 microcoulombs (μC). The charge of a single electron is approximately -1.6 x 10-19 coulombs. By dividing the total charge of -18 μC by the charge of one electron, the result is approximately 1.125 x 1014 excess electrons. This calculation illustrates the significant number of electrons involved in even small static charges.

PREREQUISITES
  • Understanding of electrostatics and electric charge
  • Familiarity with the concept of microcoulombs (μC)
  • Knowledge of the charge of an electron (-1.6 x 10-19 coulombs)

Homework Statement


On a dry day, your body can accumulate static charge from walking across a carpet or from brushing your hair.

If your body develops a charge of -18 (microcoulombs), how many excess electrons has it acquired?

i don't know what to do lol.
