Electric Field Calculation of Point Charges

In a vacuum, two point charges are placed on the x-axis: Charge A (2 μC) at position x = 0 m and Charge B (-3 μC) at position x = 4 m. Calculate the net electric field at a point on the x-axis, specifically at x = 2 m. Assume that the electric field due to a point charge at a distance r is given by the formula E = k * |q| / r², where k is Coulomb's constant (8.99 x 10^9 N m²/C²), q is the charge, and r is the distance from the charge to the point of interest.

Determine the direction of the electric fields produced by each charge at the point x = 2 m.
