ya i mean mathematically a complex valued solution. Can you give it a try i just want to check my math. By the way there are not four -q/2 charges but only two. There are four +1 charges located around the vertices of square and two -q/2 charges lie along one of the diagnol. I know that the...

Yes fortunately i do and i do find it simple. From what i did if i considered oblique sources i was getting a complex solution. This is what is bothering me by the way.

your argument was erroneous no the argument that the two other chargejs produce forces would cancel out is erroneous. In fact the two charges have a components in the direction that you just drew. The force is oblique angle so it has one component that cancels but other one does contribute.

thanks a further clarification That was very good analysis however i still need some more fundamental(i know i may sound lame but i am just beginning with real physics). How did you use coulombs law to find your relation. I got zero. Please elaborate. thanks

HI, I just have a simple question if you have a square array of charges of +1 where the charges lie on the vertices of the square(so the charges form a suare patten where 4 of them form a unit square). The way you can balance the charges is by placing a -1 charge in the center of each square or...

some modification The previous problem that i gave has some modification. I have written some details in the document. Thanks ggups

Hi, This is my first post, am excited to be here. Cutting to the chase here, i have a question that has been bothering me for a while. The problem is there is a charged cylinder with charge say +1, and i have to charges outside say at a distance 'd' from the center of the cylinder such that...
