8-EE) For BSEE. Much like Newton's law of gravity, Coulomb's law states that the force between two electrical charges varies as the product of the charges and inversely as the square of the distance between them: F = kq₁q₂/r² where F is in Newtons, q in coulombs, r in meters, and k = 9x10'Nm²/C². Given two small electrical charges q₁and a positioned on the x-axis as follows: q₁ = 4µC at x₁ =- 3m; 9₂ + 1µC and x₂ = + 2m. Find the position on the x-axis of a third electrical charge q, that experience no net force from these two.

Please include all steps

If you can show the complete solution, and complete diagram that would be great Each formula ( if it is not a general one) should be derived. You should also apply a cross-product formula to solve the first part.
