My solution so far:
E = kQ/r2
E = kQ/a2 (^r)
I think tan(45*) should be used, so it should be...
E = kQ/a2 (tan(45*))
Thank you.
Homework Answers
Forces due to two positive q charges cancel out each other. The remaining force is due to +q and-q which are at opposite corners.These two forces add up.
Final F= 2*kqQ/a2
Direction is along the diagonal from +q towards -q charge along the arrow drawn in the figure.

Basic Coulomb's law tells us that the electric field of a point
charge q, E=ke q/r2, scales with distance r
as 1/r2: when the distance increases by a factor of 2,
the magnitude of the field decreases by a factor of 4. We can write
this as E(r) ∝ 1/r2. An interesting and practically
important question is how the electric field of a group of charges
scales with distance (asymptotically) far away from the group. The
figure below depicts 3...

The charge for Q3 is not given. I could not find formula in
book. So do I take EA total 4.5 X 10^6 N/C. And use it for E? Then
set formula like so 4.5 X 10^6= (9.0x10^9)Q/(.30m)^2 and solve for
Q to get charge? I need help.
