Lab Assignment 4: Electric Charge and Coulomb’s Law
Instructor’s Overview
This lab is our first experimental foray into electricity. We start our journey with
an examination of electric charge. All of us have experienced the sparking of
static electricity when we brush against various objects in the heart of winter.
The view of lightning striking in the distance is awe inspiring. We'll begin to gain
more of a quantitative understanding of phenomena related to electric charge in
this laboratory exercise.
This lab is based on Lab 19 of your eScience Lab kit.
We will be performing Experiments 2 and 3 of Lab 19.
Here is a high-level view of the lab:
In the first part of the lab (Experiment 2), you induce a charge on various
materials and observe how they interact with other objects.
In the second part of the lab (Experiment 3), you will explore charging by
contact and induction.
Take detailed notes as you perform the experiment and fill out the sections
below. This document serves as your lab report. Please include detailed
descriptions of your experimental methods and observations.

Abstract
In this practice, we will work on the electric charge and Coulomb's law. To
understand what the subject to work on and its characteristics are about, we will
explore the nature of electrical interactions, carrying out a series of activities, and
analyzing the dependence of the interaction forces between the materials
involved.
Introduction
Electric charge is one of the basic properties of matter. Electrical phenomena,
indivisibly linked to magnetic ones, are present everywhere, be it in storms, solar
radiation or the human brain. In modern times, its properties are used in multiple
fields of activity, and electricity has become an essential form of energy
consumption and transport. Due to their electrical nature, physical bodies are
classified into conductors, which transmit electricity easily, and insulators, or
dielectrics, which offer high resistance to their passage. Semiconductors have an
intermediate conductivity between these two classes.
The essence of electricity is an electrical charge. This quality exists in two distinct
classes, which are called positive and negative charges. Electric charges of the
