**Net Force Calculation on a Point Charge**

**Problem Statement:**
What is the net force on the \(-10 \mu C\) point charge?

**Diagram Explanation:**
The diagram illustrates a system of three point charges and their relative distances:
- There are three charges labeled as \(-10 \mu C\), \(-30 \mu C\), and \(40 \mu C\).
- The \(-10 \mu C\) charge is positioned 7 cm away from the \(-30 \mu C\) charge, 24 cm away from the \(40 \mu C\) charge, and 25 cm away from the \(-30 \mu C\) charge.
- The charges are positioned in such a way that they form a right triangle.

**Options Provided:**
1. 488 N
2. 613 N
3. 554 N
4. 24 N
5. 41 N

The numerical values will further help in calculating the net force using Coulomb's Law.

**Concept Explanation:**
To find the net force on the \(-10 \mu C\) charge, we use Coulomb’s Law, which states that the magnitude of the force \( F \) between two point charges is:

\[ F = k_e \frac{|q_1 q_2|}{r^2} \]

Where:
- \( k_e \) is Coulomb's constant (\( 8.99 \times 10^9 \, Nm^2/C^2 \))
- \( q_1 \) and \( q_2 \) are the magnitudes of the charges
- \( r \) is the distance between the charges

The net force is the vector sum of forces exerted on the \(-10 \mu C\) charge by the other two charges. This involves calculating each force individually and then combining them using vector addition principles.

**Answer Choices Analysis:**
Given the options, we would typically solve the problem step-by-step as outlined, making use of given measurements and fundamental principles of electrostatics.

**Interactive Element:**
To enhance learning, students might be prompted to attempt the detailed calculations and conceptual understanding to arrive at one of the provided answers.
