Homework Statement
I'm given a chart of Force vs Seperation with the following values:
SEPARATION (m)
0.1
0.2
0.3
0.4
0.5
0.6
FORCE (N)
0.79
0.48
0.20
0.05
0.022
Where FORCE is the y-axis, and 0.1 corresponds with 0.79.
I am not given any other values. All I know is that these are measures of distance and forces between two identical, equally charged spheres.
Now I am tol to manipulate the data until I get a set of values that will form a straight line when graphed.
Homework Equations
E = kq1q2/r^2
The Attempt at a Solution
I know that Coulomb's law works out to k x q1 x q2 x 1/r^2
So if I were to multiply by r instead of 1/r^2 I should get a linear graph...
Problem is, I don't have any values for either charge.
I'm totally stumped. Can someone point me in the right direction?
