I apologize for the brevity but the forums logged me out and ate my entire post. I just want to get the information written down this time.
We have two charged beads, 12.0cm apart. What are their maximum velocities when released?
Bead A: -5.0nC, 15.0g
Bead B: -10.0nC, 25.0g
kqq/r
Ui +Ki = Uf + Kf
I have already found the potential energy of the system, but my answer for the first bead is incorrect - I am getting about 2.23 for the first bead and the book indicates ~1.77.
I thought I just needed to use Vf = sqrt(2Ui/r), but I am apparently missing part of the process. I have been at this for five hours and really have no idea how to proceed. Any help would be greatly appreciated!
