1. What is Net Electric Force?

Definition: The net electric force is the vector sum of all individual electric forces acting on a charged particle.

Purpose: This calculator helps determine the resultant force from multiple electric forces acting on a charge.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( F_{net} \) — Net electric force (Newtons)
• \( \Sigma F_e \) — Sum of all individual electric forces (Newtons)

Explanation: The calculator adds up all the electric force values you provide to give the net force.

3. Importance of Net Electric Force Calculation

Details: Calculating net force is essential for understanding the motion of charged particles in electric fields and designing electrical systems.

4. Using the Calculator

Tips: Enter at least one electric force value (required). You can add up to three forces. All values should be in Newtons.

5. Frequently Asked Questions (FAQ)

Q1: What if forces are in different directions?
A: This calculator assumes all forces are in the same direction. For vectors in different directions, you would need vector addition.

Q2: What's the unit of electric force?
A: The SI unit for electric force is the Newton (N).

Q3: Can I add more than three forces?
A: This calculator handles up to three forces. For more, you would need to sum them separately and enter the total.

Q4: How is electric force different from gravitational force?
A: Electric force acts between charged particles, while gravitational force acts between masses. Both follow inverse-square laws but have different constants.

Q5: What if I have negative values?
A: Negative values indicate opposite direction forces. The calculator will algebraically sum them.
