Charges.....Again

Unfortunately, this is a chapter about which I don't comprehend much. I tried reading the book and reviewing the exercises, but the more I read, the more I felt I didn't understand...Luckily, this past week helped a little bit more. Not as much as I would have liked, but it was okay.

Newton's Law of Gravitation is as follows:

F(gravity) = G(m1+m2)/2^2

It is really similar to Coulombs Law or something...in which k = 9*10^9

F(e) = k(q1q2)/r^2

Another equation I got from my friend is  E = F/q. And q = ne. I'm not really sure when to use either, but maybe adrenaline during the test will help me think...Anyway, the review worksheet we were given sort of helped. It reminded me that electrons are the things that exchange as opposed to the neutrons and protons.


...And this is attraction at its best.
