Coulomb's Law
Coulomb's Law calculates the electric force (F) between two point charges: F = k × (|q₁q₂|/r²). This law is fundamental in electrostatics to predict charge interactions. ScanSolve computes these forces effortlessly, providing clear visualizations.

Frequently Asked Questions
What is Coulomb's constant?
Coulomb's constant (k) is approximately 8.99 × 10⁹ N·m²/C². It's used to calculate the electric force.
How does distance affect force?
The force decreases with the square of the distance. Doubling the distance quarters the force.
Can this calculate for multiple charges?
Coulomb's Law is primarily for two charges, but superposition can be used for multiple charges.
