Chapter 2, Problem 17E

Interpretation Introduction

Interpretation:

The number of excess electrons acquired and their collective mass when your body develops a charge of $-15\text{μC}$ on walking across a carpet or from brushing your hair is to be calculated.

Concept introduction: The number of electrons is calculated by the equation

$\text{Number}\text{of}\text{electrons}=\frac{\text{Amount}\text{of}\text{charge}\text{developed}}{\text{Charge}\text{on}\text{electron}}$

To determine: The number of excess electrons acquired and their collective mass when your body develops a charge of $-15\text{μC}$ on walking across a carpet or from brushing your hair.
