Yeah, I had that in there. The parallel set is then in series with the top 11.7, and then I still can't get the right answer.

I'm not quite sure how I'm supposed to be doing this problem. Consider the circuit shown in the figure below. R = 21.3 ohms http://east.ilrn.com/graphing/bca/user/appletImage?dbid=411814203 Find the current in the 21.3 ohm resistor. I combined (serial) R with the 5.85 ohm...

I was under the impression that Gauss's Law said that the spherical shell is treated as a point charge at the center of the shell itself. But I tried all numbers of different radii, none of them would give the right answer (according to the homework website). I think I'll just address this with...

I'm having trouble with this problem: Consider a thin spherical shell of radius 14.5 cm with a total charge of +38.9 microCloumbs distributed uniformly on its surface. (Take radially outward as the positive direction.) So I need to find the field at 35.6cm from the center of the charge...

okay, false alarm. I did have the right answer, my program wouldn't accept it without the leading 0 and wouldn't tell me that that was the reason I was getting it wrong.

right, but i have to find it as a ratio of d. i can't find anything wrong with how i set it up, I made the charges proportional, and equal to each other and then solved for x, my answer should be sound, but the program won't accept it.

OK, the next thing I'd check is the direction of your electric fields. Remember that for negative charge points, the fields go toward the points and for positive charge points, the fields go away from the points.

What units is it asking for the answer in? I'm doing similar homework and it asks for the answer in kN/C not N/C.

I'm doing my first electromag homework so there will probably be a few more of these. Two small beads having positive charges 19q and q are fixed at the opposite ends of a horizontal insulating rod extending from the origin (the location of the larger charge) to the point x = d. As in the...

That was the problem. I just took the square root of the number I got (which was typoed in what you read) and continued with the problem to get the correct answer. At least I found that my concept of the problem wasn't what was flawed. Makes me feel better about my understanding of coulomb's law.

I'm having trouble even beginning this problem. I'm not quite sure how to convert from the charge, which I believe I can find, to the number of electrons shared. If someone could help me understand what I'm being asked to find, and how to find it, I would really appreciate it. The problem is as...
