Duh! I can't believe I didn't see that! Also, the answer yielded with your method is correct. Thank you very much!

Hmm by using that, I get an answer of -6.27 x 10^-14, which is incorrect...Just out of curiosity, what would be the correct angle, had I not realized that components were easier? Thanks again, especially for that godly-quick response.

Homework Statement An electron that has a velocity with x component 2.3 x 106 m/s and y component 2.9 x 106 m/s moves through a uniform magnetic field with x component 0.040 T and y component -0.12 T. (a) Find the magnitude of the magnetic force on the electron. (b) Repeat your calculation for...

Thank you very much Doc, you've saved the day once more! I just have one more question left that I'm struggling with but I'm going to try it some more. If I need help, I'll start a new thread to make everything more organized. Thank you once again Doc!

Homework Statement In Figure 24-60, we move a particle of charge +2e in from infinity to the x axis. How much work do we do? Distance D is 6.30 m. http://img216.imageshack.us/img216/6987/fig2460.th.gif Homework Equations U = kQq/r U=-W The Attempt at a Solution Ok since...

For part A, when you say you used Ugrav = final kinetic energy + Spring potential energy, could you please elaborate as to how that was accomplished? If final kinetic energy is 0.5*mass*velocity, how did you calculate velocity? For part B, I run into the same roadblock, the veocity. For C, I...
