NascentOxygen, sorry! Next time I will upload a picture with it. As for the help, thanks guys! I forgot about subst. i1 into both equations. The only question I have remaining is for EQ3. Where is the sign problem exactly? The way I have it set up, it's kind of "awkward" for the junction rule...

Conceptual question help--Electric fields, potentials, etc.
Homework Statement
1) Assume that the electric field E is equal to zero at a given point. Does it mean the electric potential V must also be equal to zero at this point? If not, provide an example to prove your answer. if you think...
Right, I'm aware the force must be balanced. However, I believe I'm missing something. I have gravity and tension as forces; gravity acting straight down onto the sphere and Tcos30 in the +y direction. I'm assuming you incorporate the tension in the +x direction, as well, to put it into...
Charged sphere hanging from a string--Find the charge?
A small, plastic sphere of mass m = 126 g is attached to a string as shown in the figure. There is an electric field of 151 N/C directed along the + x axis. If the string makes an angle 30 degrees with the y-axis when the sphere is in...
