, Purpose:
This experiment was designed to demonstrate to students equipotential lines
and electric field lines for 2d charge configurations.
Theory:
An atom consists of positively charged protons, negatively charged electrons
and neutrally charged neutrons. In nature, atoms are normally found with no net
charge, meaning the number of positively charged protons is exactly equal to the
number of negatively charged electrons. However in some instances, an atom can
m
er as
become electrically charged. There are two states of charges an atom can become:
co
eH w
positive and negative. Because protons are held tightly within the nucleus of an atom
o.
rs e
and cannot be removed, electrons, which exist in a diffuse cloud that orbits around
ou urc
the nucleus, determine the final charge of the atom. An atom is negatively charged
when the number of electrons is greater than the number of protons. It is positively
o
aC s
charged when the number of electrons is less than the number of protons. Charged

atoms can either attract or repulse one another, creating an electrostatic force. Like

where r is the distance between the two charged atoms, and k is a constant (k = 9.0 x

An electrical field is defined as the electrical force per unit charge. The magnitude of
the electrical field a distance r away from the source charge is represented by
