Description
This is a basic simulation showing the force of attraction or repulsion between two charged objects. The charge
on each object and the positions of the objects can be changed. The resulting forces are shown by force vectors,
and the numerical magnitude is also shown.
This simulation shows you the magnitude and the direction of the force that acts on each of two charged objects
due to the other object. Use the sliders or input boxes to change the amount of charge on each of the two
objects. Move the charges aroun
amount of force that acts is shown. Graphs of the force magnitude vs. the distance between the two objects (r)
and force magnitude vs. the magnitude of the charge on q1 can be viewed. The grid spacing is 1 m, and the
objects will "snap" into place if placed near an intersection on the
and watch how the force vectors change magnitude and direction. The

Q1:What dependence does the force have on distance? Think about both the shape of the plot and the
equation for the Coulomb force presented in the theory section.
Q2:What dependence does the force have on the size of the charge? Think about both the shape of the
plot and the equation for the Coulomb force presented in the theory section.
Q3:Will the force change if you doubled one of the charges? If so,how?
Q4:Will the force change if you doubled the distance between the charges? If so, how?
Q5:Recall that the force of gravity can be given by
91921
F = k
r2
And looks a lot like Coulomb's law. What similarities and differences are there between these two
forces? (HINT: Think about the sign of the force.) How do the forces compare in size? (HINT: As an
example, consider two electrons at a distance ofr= 10-12m(about the size of an atom). Remember
thatan electron has a mass of m = 9.11 × 10-31kg and a negative charge of magnitude e =
1.9 x 10-19C.) (HINT 2: You don't have to calculate the specific number, but just compare the powers
of 10!!)
