Hello all, I have been having some trouble with deciding what to do this summer and was hoping those of you with experience in the area could give some advice. My three options are: 1. Research at my current university. The pay is $8/hr, with no housing or food allowance. This is the lab I...

Thank you for the explanation :) I completely understand the logic behind it (thanks to you), but I just can't figure out how to translate it into math. I just handed it in, but I have understood every other homework problem this year so I'm not too worried! He gives solutions, so I'll post...

Why are we looking at the surface of the sphere? We only have center charge and radius a at the moment, unless you just jumped ahead. Also confusing me is that shouldn't the surface of the sphere have the same V as at a since it's a conductor? Or is it just an equipotential with a different...

I am unsure of how to do part 1. I am thinking of something similar to the work to build a solid sphere of charge, but don't know how to translate it to a surface. Any help? :)

Yes, and I did it that way. However our professor also wants us to figure it out this way :( thanks though :)

Homework Statement A point charge q is at the center of a spherical conducting shell of inner radius a and outer radius b. How much work would it take to remove the charge out to infinity? Homework Equations Potential, W = 1/2qV The Attempt at a Solution I am going at this in...

Oh man I am sorry, I will be able to complete both research courses this semester without a problem. I was talking about future semesters! I am essentially wrapping up one project this semester, and if maintaining both would be impossible I would end with this project rather than go through the...

I am currently doing research for credit with two professors (separately), one in theoretical particle and the other in experimental atomic/molecular. I have an interest in both, however I think that one may increase in time commitment and make me unable to perform both simultaneously. Does...

I got to: z^2 = (a^2(x^2 + y^2)) / (1 - a^2), at which point I can just call it a cone based upon the standard equation of a cone. Right?!

a < 1 for this problem, though the professor did say a special case arises for a > 1 :)

I am not sure what I mean haha. I know that if n is a unit vector, then it will be n = a. I am not sure how it is if it is not a Cartesian unit vector. Thank you Dick! That was very clear and exactly what I needed. z = a√(x^2+y^2+z^2) brings back memories of multivariable calculus, but I am not...

1. Position vector r DOT n(hat) = a, where n(hat) is a unit vector and a is a scalar. 2. Position vector r DOT n(hat) = a times (magnitude of) r. I know the first question describes a plane of n = a, if n is a Cartesian unit vector. However I don't know if I should worry about other unit...

Okay to answer some questions. I came in with a lot of credit from ap testing, hence my flexibility. The program allows you to combine undergrad and grad coursework, and to earn a bs/ms if you wish. I thought itd be a good idea to give myself an extra summer and school year to do research and go...

Yes the U.S and I plan to stay for my PhD here.

Hey all, I am interested in doing a program at my university that would allow me to take ~11-13 graduate courses (including three for research thesis) and get me an M.S in the standard four years one would get a B.S. I want to be the best applicant for a PhD program and I feel that if I left...
