Ok so I've checked over this several times, and I plugged it into my calculator wrong, so Flux2 = 0.8. However, it is still wrong! Does anyone know if there's some trick to it that I'm missing?

I think I may have found my mistake: wouldn't Flux2 = (.12) (.05) (400) cos (90 - (inverse sine (.04/.12)) = .01424 ? Then net flux would be -0.1458?

Here is the figure!

Homework Statement The electric field has been measured to be horizontal and to the right everywhere on the closed box shown in the figure. All over the left side of the box E1 = 80 V/m, and all over the right, slanting, side of the box E2 = 400 V/m. On the top the average field is E3 = 260...

Ohhhhh wow I can't believe I was looking at it that way... And I googled the force lines and the line is headed in the -y direction... thank you both for patiently guiding me to finding my stupid mistake! o0)

Hmm well we haven't done that in class yet, but I think I can do it... Am I correct in drawing my electric field line from the electron's location at <-3x10^-8, 48000, 0>?

Oh whoops! I meant negative electric field... So what about the x-axis value?

I'm thinking about the way I would draw my answer as a vector on a graph that includes the two charges... It doesn't make sense to me that that the force vector would be <0, -7.68x10^-15, 0> so that it extends downward on the y-axis directly below the charges, instead of extending downward...

Well an electron has a negative charge, so after being multiplied to a negative electric field, the force would be pointing in the positive direction.

Yes I did, and the electric field is pointing in the +y direction, and the force is pointing in the -y direction... Is that correct?

Homework Statement A dipole is centered at the origin, and is composed of charged particles with charge +e and -e, separated by a distance 9 ✕ 10-10 m along the y axis. The +e charge is on the -y axis, and the -echarge is on the +y axis. An electron is located at <-3 ✕ 10^-8, 0, 0> m. What is...

Oh! That makes a lot more sense now! Thanks for all your help!

The only possibility I can see from this is that one of them would be 1.11, which doesn't fit the limits the problem gave us...

Would it emit photons from N=3 to N=2, N=2 to N=1, and N=3 to N=1? So it would be .64 and .37eV?

Oh... Also I just realized that -13.6/N^2 is only for hydrogen atoms, I will need to devise a different approach...
