Net Electric Force Formula:
Definition: The net electric force is the vector sum of all Coulomb forces acting on a charge due to other charges in the system.
Purpose: This calculator helps determine the total electrostatic force experienced by a charge in the presence of multiple other charges.
The calculator uses Coulomb's Law:
Where:
Explanation: The calculator sums the forces from each charge pair to determine the total force on the main charge.
Details: Calculating net electric force is fundamental in electrostatics, helping predict charge behavior in electric fields and designing electrical systems.
Tips:
Q1: What is Coulomb's constant?
A: It's a proportionality constant in Coulomb's Law, approximately 8.99 × 10⁹ N·m²/C².
Q2: How do I represent negative charges?
A: Simply enter negative values for charges (e.g., -1.6e-19 for an electron).
Q3: What units should I use?
A: Charges in Coulombs (C), distances in meters (m), result is in Newtons (N).
Q4: Does this calculate direction of force?
A: This calculates magnitude only. Direction depends on charge signs and geometry.
Q5: What if charges are at different angles?
A: This calculator assumes colinear forces. For 2D/3D systems, vector components would be needed.
