What is the Net Force on Charges in a Square?

Homework Statement

F=Kq1q2/r^2
E=kQ/r^2

Answer choice E is not listed in screenshot, but states that there is no Net force on the Charge. I picked E, but I'm second-guessing myself.

What made you choose E? Are there other options that seem plausible to you which make you second guess yourself?

Well, I guess I was hoping for a more quantitative way of understanding the vector sums in this equation, without having supplied values.

Ultimately I just plugged in some variables and my answer held up.
