Chapter 8, Problem 8.4E

Interpretation Introduction

Interpretation:

The statcoulombs in a coulomb is to be calculated.

Concept introduction: The force of attraction between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of distance between them. The formula for determining force of attraction is given below.

$F=\frac{q_1{q}_2}{4{\text{πε}}_{\text{o}}{r}^2}$

In the above equation, $F$ is the force of attraction between two charges, $q_1$ and $q_2$ are the charges, $r$ is the distance between charges and ${\text{ε}}_{\text{o}}$ is the constant. The value of ${\text{ε}}_{\text{o}}$ is defined as $8.854\times {10}^{-12}{\text{ C}}^{\text{2}}{\text{ J}}^{-\text{1}}{\text{m}}^{-\text{1}}$.
