Expert Solution
Step 1
According to coulomb's law the field at point (x,y) due to a charge at (x'y') is given by,
Coulomb's law also follows superposition principle of superposition according to which the electric field at point due to a system of charges is given by the sum of electric fields at that point due to individual charges, mathematically,
The situation can be evaluated by setting the coordinates as shown below,
