Chapter 4, Problem 4.42QP

Interpretation Introduction

Interpretation: Given pairs of charged particles has to be arranged in order of increasing magnitude of attractive force.

Concept Introduction:

Coulomb’s law states about the force between the two charges.  In chemistry, Coulomb’s law states that the force exhibited between two charges is directly proportional to the product of two charges and inversely proportional to the square of distance between the two charges.  In form of equation it can be depicted as,

$\text{F}\propto \frac{{\text{Q}}_{\text{1}}\times {\text{ Q}}_{\text{2}}}{{\text{d}}^{\text{2}}}$

Where $Q_1$ and ${\text{Q}}_{\text{2}}$ are the amount charge on the two ions considered and “d” is the distance between two ions.  The magnitude of the attractive force does not have any sign.

To arrange the pairs in increasing order of magnitude
