ya I am pretty sure i get the intuition behind it, ill take it that i just use Gaussian pillbox for each of the dielectrics that it touches and see where that takes me

i will certainly keep that in mind, thanks for the advice :)

ok, you that's what i was going for, but do u know if each dielectric is effected by just the plate touching it, or everything including the other dielectric?

the problem with that is, my parents (mainly my mother) is over controlling and doesn't want me to leave the state. id love to go to a different college, and we have the financial resources for out of state, its just... I am not exactly sure, but i can't leave, and i assume u of m is my best...

no no no, by i can easily get an A, i mean that i have the ability to get an A, me and my physics teacher talk all the time about it. i currently am self teaching myself Griffiths EM, and go to her if i need help. its not that its an easy class, its just i won't have a problem.

wat are my chances to get into U of M physics program, or engineering programs GPA: 4.1 (weighted), 3.95(unweighted) ACT: I am only a soph. atm, and i took ACT at end of fresh year and got a 26 AP: next year I am taking AP physics, AP gov, and AP statistics (talked to all my teachers for those...

question: so here is what my problem is. there are two dielectrics between a parallel plate capacitor. distance between the two plates is '2s' and each dielectric is 's' long. each plate has a charge of \itshape \sigma (top being pos. and bottom being neg. and doesn't give an area) how would i...

i thought... U=-\vec{p} \cdot \vec{E} but idk if that really changes much.

well your halfway there if you did the math right on both of those. a major concepts of electrodynamics is the rule of superposition, which states that the electric fields at any point is the sum of all the electric fields due to each electric charge effecting your system.

hopefully this can point you in the correct direction to go into solve this problem. one of the main concepts in electrodynamics is superposition. superposition says that the electric field at a point is the sum of all the electric charges acting on that point. hopefully the fact the...

well i don't know how in depth you book is, but I am going to assume that the marble will have angular momentum from rolling along with the sliding (unless its rolling at a speed of which there is no sliding), and the question makes a point of saying the coin won't roll so it might have...

well u know that total distance traveled between each station is 1.8km so d_{tot}=d_{1}+d_{2}+d_{3} and you already told us the speed it will be going during d_{2} (94km/h) so do u have any equations that u have the change of displacement and the constant velocity, and it will give u the time...

can you show your work so maybe we can see where you went wrong, and we could try to help you from there?

for Q1: i couldn't read ur writing, so i can't tell you if you are right or wrong, but some things to keep in mind for at least the first one (i didn't read the second problem yet) are superposition ~that u can take the sum of the force applied from each of the other electric charges, and that...

ill try to provide some intuition behind this type of problem. a flux is the amount of a volume passing a point per time. in this type of problem we can use electric field lines as our volume, and the point being the surface of the sphere. if one assumes that the field lines start at the...
