1. What is Electric Force in an Electric Field?

Definition: This calculator computes the force experienced by a charged particle in an electric field using the formula F = q × E.

Purpose: It helps students and professionals in physics and electrical engineering calculate the force on charged particles in electric fields.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The force on a charged particle is directly proportional to both its charge and the strength of the electric field.

3. Importance of Electric Force Calculation

Details: Understanding electric forces is crucial for designing electrical systems, analyzing particle behavior, and solving physics problems.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the direction of the electric force?
A: The force direction depends on the charge sign - positive charges experience force in the field direction, negative charges opposite to the field.

Q2: What are typical values for electric field strength?
A: Near point charges, fields can be millions of N/C, while household fields are typically under 100 N/C.

Q3: Can I use this for moving charges?
A: This calculates instantaneous force. For moving charges, additional magnetic force must be considered.

Q4: What if my charge is negative?
A: Enter the absolute value - the calculator gives magnitude. Direction would be opposite the field.

Q5: What units should I use?
A: Use Coulombs for charge and N/C for field strength for results in Newtons.
