1. What is the Electric Force Formula?

Definition: This formula calculates the force experienced by a charged particle in an electric field.

Purpose: It helps physicists and engineers determine the force acting on charged particles in electric fields.

2. How Does the Formula Work?

The formula is:

Where:

• \( F \) — Electric force (Newtons)
• \( q \) — Electric charge (Coulombs)
• \( E \) — Electric field strength (Newtons per Coulomb)

Explanation: The force is directly proportional to both the charge and the electric field strength.

3. Importance of Electric Force Calculation

Details: Understanding this force is crucial for designing electrical systems, particle accelerators, and studying fundamental physics.

4. Using the Calculator

Tips: Enter the charge in Coulombs and electric field strength in N/C. Both values must be positive.

5. Frequently Asked Questions (FAQ)

Q1: What if the charge is negative?
A: The calculator uses absolute values. A negative charge would mean the force direction is opposite to the field.

Q2: What's a typical electric field strength?
A: It varies widely - from 100 N/C near Earth's surface to millions of N/C in capacitors.

Q3: How small can the charge be?
A: Elementary charge is ~1.6×10⁻¹⁹ C, but the calculator can handle any positive value.

Q4: What units does this use?
A: Standard SI units - Coulombs for charge, N/C for field, and Newtons for force.

Q5: Does this include magnetic forces?
A: No, this is purely for electric forces. Magnetic forces require additional calculations.
