ohhhhhhhhhhhh ok. This makes sense now. lol Thanks for your time and help. Physics is starting to make more sense now :smile:

the thing is for the answer it says Number: ____ N/C or V/m and I cannot use vector letters, that's what is confusing me

ok I think I'm completely lost. :confused: I find the electric field from each charge: E1= (8.99E9*1.602E-19*7.59E-9) /(0.065)^2= 2.58724 E-15 C E2= (8.99E9*1.602E-19*-1.09E-8) /(0.065)^2= -3.71554 E-15 C E3= (8.99E9*1.602E-19*1.15E8) /(0.065)^2= 39.2007 C E4=...

well that would be 3i+4j, correct? Would I do the cross product?

ok so I found that with the formula F=kq1q2/r^2 in the diagonal direction where the charges are being repulsed that F= 6.50731 E-15 and diagonal direction where charge are drawn inward F=-37.1554, if my calculations are correct, would I just take the dot product and multiply them together to get...

gotcha, I'll do this when I have break between classes. :smile:

ohhhhhhhhhh, then in that case would I Just find F for each particle then add them up to get the sum?

ohh wait, is it F=kq1q2/r^2 where q1 is one of the particles and q2 is the fixed positive test charge?

that makes sense, but if we have a constant Q in this case, the positive test charge, as well as equidistant particles from that test charge then wouldn't E be the same for each particle? ie. E1= 8.99E9*1.602E-19/ (0.045962)^2 Im kinda confused on how they want use to find the magnitude of the...

omg, not k, I meant q. I have no idea why I typed k. :redface:

so is K the positive test charge in the center of the field?

ohhh, but isn't electric field E=(kq)/r^2?

lol, well good morning. So if the vector fields are electric fields produced by each particle then was my original attempt correct my finding the electric fields and adding them up?

* face palm * I need to stop doing homework so late, I got it now. Thank you soooo much for your help and time. I really appreciate it! This will certainly be a question I'll review for an upcoming exam :smile:

ok the numerical value is correct but the units are still wrong! lol
