### Understanding the Electric Field Vector Problem

#### Problem Statement:
What is the correct electric field vector at point P due to source charge q = -25C? Use k = 1x10^10 Nm²/C².

#### Diagram Explanation:
The diagram is a right-angled triangle that provides the positions of the source charge and the point where the electric field is to be determined. Here are the details of the diagram:

- The source charge \( q = -25C \) is located at one corner of the triangle (left).
- Point P is the point where the electric field is being calculated and is located at the other corner of the right triangle.
- The distance between the source charge and the base of the triangle to point P is shown as 4.0 meters horizontally (to the right) and 3.0 meters vertically (upward).

The positive direction is defined with respect to the conventional coordinate system: right as the positive x-axis, and up as the positive y-axis. The electric field produced by a negative charge points toward the charge.

#### Answer Choices:
1. 
\[
\left( -\frac{3}{5} \times 10^{12} i - \frac{4}{5} \times 10^{12} j \right) \, \text{N/C}
\]

2. 
\[
\left( \frac{4}{5} \times 10^{12} i - \frac{3}{5} \times 10^{12} j \right) \, \text{N/C}
\]

3. 
\[
1 \times 10^{12} \, \text{N/C}
\]

4. 
\[
\left( \frac{4}{5} \times 10^{12} i + \frac{3}{5} \times 10^{12} j \right) \, \text{N/C}
\]

5. 
\[
\left( \frac{3}{5} \times 10^{12} i + \frac{4}{5} \times 10^{12} j \right) \, \text{N/C}
\]

To determine the correct electric field vector at point P due to source charge \( q = -25C \), the following formula for the electric field due to a point charge is applied:

\[
\vec{E} = \frac{k
