1. The problem involves calculating the electric field at a point due to multiple point charges using vector addition and Coulomb’s law.
2. For each charge, compute the magnitude of the electric field using E = k|q|/r², where k is Coulomb’s constant, q is the charge, and r is the distance from the charge to the point.
3. Determine the direction of each electric field vector based on the sign of the charge and its position relative to the point.
4. Resolve each electric field vector into x and y components using trigonometry (cosine for x, sine for y).
5. Sum all x-components and all y-components separately to find the net electric field components.
6. Use the Pythagorean theorem to calculate the magnitude of the net electric field: E_net = √(E_x² + E_y²).
7. Find the direction of the net electric field using θ = tan⁻¹(E_y / E_x), adjusting the angle for the correct quadrant.
8. Express the final answer with appropriate units (N/C) and direction (angle from a reference axis).
