1. ### Method of Images

Great! Thanks!
2. ### Spherical conductors

That makes sense! I think I was on the right track. Thanks!
3. ### Spherical conductors

1. Homework Statement thin wire connecting two conductors, a big sphere and a small sphere. What sphere has the most charge? 2. Homework Equations 3. The Attempt at a Solution The charge will want to distribute itself over the entire surface area of the two conductors...
4. ### Method of Images

1. Homework Statement Two point charges sit on either side of large grounded conducting plane. Give an expression for the force experienced by the charge on the left hand side. There is a neg charge on one side and positive charge on the other side. 2. Homework Equations The...
5. ### Infinately long magnet

1. Homework Statement What is the force from an infinitely long cylindrical magnet on a magnetic dipole? 2. Homework Equations M=Mz (given in problem) 3. The Attempt at a Solution My argument for this solution that since the magnetization is in the z direction and the cylinder...
6. ### NACL in Water

1. Homework Statement Imagine water in a metal bowl that is open to air. This metal bowl is grounded. You add some NaCl to the water. What would the distributions of the ions look like in the water. 2. Homework Equations I think this doesn't need equations, but just general...
7. ### Spherical conductors

Great! Thanks!
8. ### Spherical conductors

1. Homework Statement Two equal sized spherical conductors are connected with a wire. Charge is placed in one conductor. What is the electric field look like? 2. Homework Equations E=q/4pi*ep*r^2 3. The Attempt at a Solution I think that since these two conductors are...
9. ### Conductors and electric field problem

Re: Conductors Ok. That seems to make sense to me. That seems more in line with my original train of thought. Thanks!
10. ### Conductors and electric field problem

1. Homework Statement What would the electric field lines look like if two opposite charges were placed within an infinite plane conductor? 2. Homework Equations None that I am aware of. 3. The Attempt at a Solution I know that electric field is 0 inside of the...
11. ### Electric Potential Cone

Ah. That makes a lot of sense. Thank you!
12. ### Electric Potential Cone

1. Homework Statement I am basically given a cone with uniform volume charge and told to find the area of highest electric potential. 2. Homework Equations I want to use the equation: V= q/4piEr 3. The Attempt at a Solution I am having trouble finding anything in my book. I...
13. ### Is this a traveling wave?

1. Homework Statement Is this a traveling wave? If so, find the speed and direction. e^-(a^2y^2+b^2t^2-2abty) 2. Homework Equations Probably relevant to know the differential wave equation. 3. The Attempt at a Solution I have a feeling that this is a traveling wave as it is...
14. ### Complex number in Denominator

Thanks very much for all the help. I did get this right thanks to all your help!
15. ### Complex number in Denominator

If I convert the denominator as given in the problem I end up with: i r^2 sin(x)+r^2 (-cos(x))+1 I don't see how I can make a conjugate with 3 variables here? Am I missing something? I have went over this several times in attempt to make sure I hadn't made a mistake......
