Force on Charge Equation:
| From: | To: |
The force on charge equation (F = qE) calculates the force experienced by a charged particle in an electric field. This fundamental principle in electromagnetism describes how electric fields exert forces on charged objects.
The calculator uses the force on charge equation:
Where:
Explanation: The force is directly proportional to both the charge magnitude and the electric field strength. The direction of the force depends on the sign of the charge relative to the electric field direction.
Details: Calculating the force on charged particles is essential for understanding electrical phenomena, designing electrical systems, particle accelerators, and analyzing electromagnetic interactions in various applications.
Tips: Enter charge in Coulombs and electric field strength in Newtons per Coulomb. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is the direction of the force?
A: For positive charges, force is in the direction of the electric field. For negative charges, force is opposite to the electric field direction.
Q2: What are typical charge values?
A: Elementary charge is 1.6×10⁻¹⁹ C. Common charges range from microcoulombs (10⁻⁶ C) to millicoulombs (10⁻³ C) in practical applications.
Q3: What are common electric field strengths?
A: Typical values range from 100 N/C (fair weather atmospheric) to 3×10⁶ N/C (air breakdown field) and higher in specialized equipment.
Q4: Does this equation work for both static and dynamic fields?
A: This basic form applies to static electric fields. For time-varying fields, additional considerations may be needed.
Q5: How does this relate to Coulomb's Law?
A: F = qE is derived from Coulomb's Law, where E represents the electric field created by other charges acting on charge q.
