another series on an existing plot, take the following steps:

Left click on the plot.

Choose "Select Data" and then "Add" an additional series to your plot.

Highlight the appropriate

x

$-$

$$and

y

$-$

values from the model.

$[1\mathrm{.}4]$

$$Question:

a

$.$

$$Create a column that will contain the

x

$-$

values of your model plot. In

this case,

$1$

$\backslash$tau

$2$

$.$

b

$.$

$$Fill the column with a range of values that is appropriate for your data. If

you are not sure, make an educated guess and this can be adjusted after

you find your data. The specific length of the column does not matter,

since this is not real data. Just make sure there is a sufficient number of

points to get a smooth line.

c

$.$

$$Create a new column that will contain the

y

$-$

values of your model plot.

In this case force,

F

$.$

d

$.$

$$In this new column, calculate

y

$$for each

x

$$using the model Eq

$.$

$(1\mathrm{.}1)$

$,$

and the given

k

q

$1$

q

$2$

$$value$.$

e

$.$

$$Plot the model of

F

$$vs

$.$

$1$

r

$2$

$$on the same plot that contains your data.

f

$.$

$$Format the model so that it appears as a solid line, not as distinct points.

g

$.$

$$Add a legend to label the different parts of your plot.
