SUMMARY
The discussion centers on determining the unknown charge in a right triangle configuration where the electric field is directed solely in the -x direction. The key conclusion is that the absence of a y-component in the electric field indicates that the charge must be negative, as it attracts positive test charges. To find the unknown charge, one should apply the formula for the electric field due to a point charge, specifically using the equation E = k * |q| / r², where E is the electric field magnitude, k is Coulomb's constant, and r is the distance from the charge.
