Three charges with magnitudes 2.0 μC, -5.0 μC and 2.0 μC are placed at the vertices A, B, and C of the right triangle ABC, respectively. In the triangle ABC angle B is the right angle and AB = BC = 0.2 m. Point P is the midpoint of the hypotenuse AC. What is the magnitude of the electric field at point P? The proportionality constant in Coulomb's law is k = 8.99×109 N m^2/C^2.
