Ok, I am still struggling with this.
If i used y=mx or in this case F=m(1/r^2) I am going to get the same answers am I not?
I can't see the difference between F=m/r^2 and F=m(1/r^2) where m is equal to kq.
Thank you very much - I knew it was something fundamental.
I have been out of school for several years and am taking a course to upgrade and the formula for the graph of a line is something I have completely forgotten!
So I need to manipulate my F=kq/r^2 into a form that matches y=mx + c...
