Here I plotted the the function of x, is this what you asked for?

isn't the test charge q2=-3.0 nC <0?? it is supposed to be between the two positive charges on the line x, I seems logic!

I first didn't know where the charge would be located at equilibrium so I tried to get a general formulas from E1j+E3j=0 then E1i+E3i=0 from the first equation I deduced that y would be zero, so the charge would be located at the x-axis then from the second equation I got the locations on the x...

Hi Berkaman, thanks for your response, here is the full exercice: and here is my answer: Thank you!

Homework Statement The equation x^2+3x-0.45=0 has two solutions x1=0.14 and x2=-3.14, these are supposed to be the locations at which the electric charge is in equilibrium with two other charges, should I use the first derivative to see at which location the charge will be stable? Homework...
