Chapter 20, Problem 43A

To determine

To Complete:The problem using Coulomb’s law.

Explanation of Solution

Introduction:

In accordance with the Coulomb’s law, electrostatic force between two charged particles can be obtained by:

$F=k\frac{q_1{q}_2}{r^2}$

Here, k is the Coulomb’s constant, $q_1$ and $q_2$ are two charges and ris the distance between them.

The complete problem can be:

A very small sphere is given a charge of $6.25\text{μC}$ . Find the electric force on it due to another charged sphere placed $2\text{ m}$ away and having charge $3\text{μC}$ .
