Great! Thanks!

That makes sense! I think I was on the right track. Thanks!

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

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. Homework Equations The electric...

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

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. Homework Equations I think this doesn't need equations, but just general understanding...

Great! Thanks!

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? Homework Equations E=q/4pi*ep*r^2 The Attempt at a Solution I think that since these two conductors are connected by a...

Ok. That seems to make sense to me. That seems more in line with my original train of thought. Thanks!

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

Ah. That makes a lot of sense. Thank you!

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

Thanks very much for all the help. I did get this right thanks to all your help!

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...

Homework Statement Express (see attachment) with a real denominator Homework Equations Not sure if there is really relevant equations to use here. The Attempt at a Solution First I multiply the top and bottom by the exponential. That gives me e^ix/(e^ix-r^2). I think this is...
