1. What is Electric Field Intensity?

Electric field intensity (E) is a measure of the electric force per unit charge experienced by a charged particle in an electric field. The formula E = m × a / q relates the electric field to the mass, acceleration, and charge of a particle in the field.

2. How Does the Calculator Work?

The calculator uses the equation:

Where:

• \( E \) — Electric field intensity (N/C)
• \( m \) — Mass of the particle (kg)
• \( a \) — Acceleration of the particle (m/s²)
• \( q \) — Charge of the particle (C)

Explanation: This equation comes from Newton's second law (F = m × a) combined with the definition of electric field (E = F/q).

3. Importance of Electric Field Calculation

Details: Calculating electric field intensity is crucial for understanding the forces on charged particles in fields, designing electrical systems, and analyzing particle motion in fields.

4. Using the Calculator

Tips: Enter mass in kilograms, acceleration in meters per second squared, and charge in coulombs. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are typical values for electric field intensity?
A: In everyday situations, electric fields are typically a few N/C. Strong fields near charged objects can reach thousands of N/C.

Q2: How does this relate to Coulomb's Law?
A: This is a different perspective - instead of calculating field from a source charge, we're calculating it from the effect on a test charge.

Q3: Can this be used for uniform fields only?
A: This calculation gives the instantaneous field at the particle's location, valid for any field if the acceleration is known.

Q4: What about relativistic effects?
A: This is the non-relativistic form. For particles approaching light speed, relativistic corrections would be needed.

Q5: How does direction factor into this?
A: The electric field vector points in the same direction as the acceleration vector for positive charges, opposite for negative charges.
