    How to Calculate Torque on a Dipole Near a Grounded Plate

    Well first define p - I'll give you that p=pcostheta(rhat)+psintheta(thetahat) So then, N=p x E=((p^2)/(4pie0(2z)^3)*[(costheta(rhat))+(sintheta(thetahat))] X[(2costheta(rhat)+(sintheta(thetahat))] The N that I gave you can be simplified further - in its simplified form you will get the...

    How to Calculate Torque on a Dipole Near a Grounded Plate

    I have attached a rough (very ugly) sketch of what the mirror charge configuration should look like. E=[p/((4pi*e0)*(2z)^3)]*(2costheta(rhat)+sintheta(thetahat) now your p is going to equal what?

    How to Calculate Torque on a Dipole Near a Grounded Plate

    Here's hint number one: where is the image dipole? And did you account for it in your equation of E? You need to use the method of image charges for this problem, Griffiths explains the topic sufficiently if you need any reference.

    Programs Is it possible be a Physics major w/o HS Physics?

    I did not take any physics in H.S, and I am a second semester physics and astronomy major. Trust me, even the kids that did, still bang their heads against walls just as much as I do during some of the problem sets.

    Do i need mechanics to learn electricity and magnetism?

    The same thought process that goes into evaluating a mechanics question goes into evaluating an E&M question. Let's say you get to the subject of a system of charges - understanding that the total force is the superposition of all the charges together. A simple concept, but it also appears in...

    Overcoming Test Anxiety: How to Relax and Ace Tests in College

    for test anxiety - what helps a lot of people (including myself) is working out before an exam. A quick run and shower before an exam can help a lot of people relax. Before an exam I always used to run through the daunting list of rolling implications - If I don't score well on this test, then...

    Getting a tutor to help you solve physics or mathematics problems

    I think, and I hope others agree, that there is a distinct difference from when a tutor gives you an answer or a tutor gives you hints or strategies to solving the problem. Or even the tutor giving you a similar problem and going through that step by step. You are probably smart enough to know...

    Whats the purpose of fraternities?

    Well yes - the houses are usually built by the organization itself - but some campuses struck a deal with a lot of the organizations - majority of the fraternities in universities are on rows or quads - the land around them is usually campus property. So although the houses themselves may not be...

    Stars from outside the atmosphere

    The atmosphere is always in between the light that enters our eyes from outside of space! Which is why almost any light that passes though the atmosphere has the chance of being affected. All the dust/pollution also play an affect in scattering the light. The turbulence of the atmosphere...

    The Learning Curve of Math and Engineering (the advantage of time)

    hm I believe the debate is being thought of a little two linearly. My opinion: The basis of fantastic art work (now most of you have been using this word a little flimsily for art in general can encompass theater, dancing, music, photography, sketching, forms of writing etc - in my definition of...

    Career guidance for a community college student

    unless your hopelessly middle middle class haha. The community colleges I know of are well under 10k a year so a combination of things would transpire a major reduction of your tuition bill. You should look into websites such as fastweb.com - a ton of scholarship opportunities, and a bunch of...

    Is It Too Late to Find Summer Research Opportunities in Seattle?

    i think it depends on what topic you intend on studying - but all topics require dedication and forcing yourself to learn a little something everyday

    Where is the center of the universe?

    hmm I have a quick question - if we make the big bang analogous to a huge explosion, then would that not that contradict the uniformity of the universe? A popular example of showing how the universe is a little different from the common definition of "explosion" is dropping a balloon full of...

    Is It Too Late to Find Summer Research Opportunities in Seattle?

    agree with it being too late, and the self- studying idea. Perhaps take a hand at learning a programming language. Useful, and plenty of resources for self-study.

    What's the male/female ratio in astrophysics?

    Surely dear friend you are not suggesting that women enter the field of astrophysics because it's easier. I do not know what school you are in, but in my program you best believe I have to take that quantum class - and I for one am looking forward to it. Look I understand that it easy to believe...
