your visualization seems to be the case. Thank you so much. Quite clear now.

Then how do i figure out the total voltage from two different particles? I can only think of taking a scalar value between one charge and the point Q1, and doing a scalar addition of that voltage with the voltage between the other and point Q2. Do i simply do this for all the particles to get a...

V at Q1 should be.. = -15900i - 15900j + 4440i - 8880j = -11460i -24780j = 27301r N*m/C I mean q at that location. So |PE| would be qV = 27301* 2.8e-6 = 0.0764 J

Homework Statement Homework Equations V = kQ/r PE = Vq The Attempt at a Solution Tried a lot of ways... get an order of magnitude less than the answer and also off by a bit too. Please help. I think you are supposed to take V at each location then multiply by q since this is PE. I carry...

Makes sense. thanks a lot!

What do you mean a leading coefficient in the third row at the fourth column? not third column? Also its called Elementary Linear Algebra, Applications Version and its by Howard Anton and Chris Rorrers. In fact it does state these properties of having all zeroes except for the leading...

Hey guys, lurked here a bit, but now I'm in this new math course right. So anyway it seems like a completely new language to me. There's some discussions about reduced row echelon form in the textbook I'm using. I was taught (before going into the course) that the object was to get leading 1s in...
