Thanks again for your help everyone!

I got it with all of your help, the (a) part anyway. I just don't know what to do about the (b) part. I think I need to find a Physics for Dummies book. I don't know how I'm going to get through this class. Its going to be a long semester...

YAY! Thank you so much! Now I just have to figure out how to do the second half and I will be done. I just have no idea where to even start. It has been so long since I did any of this and I don't remember much. Will you please just help me get started?

Sorry from a different problem (that I did get right) It should have been 2.622X10^-6 and 1.155X10^-5 I was just looking at the wrong page when I typed that.

Well I thought that when the signs are the same the force is opposing so the sign should be neg and when the signs are different the force is attractive so the sign should be pos but when I tried that it didn't work. I understand what you mean but I don't know how to calculate it. Take the...
