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.

What is gravity?

Gravity is the force that attracts two bodies toward each other, with its strength depending on their masses and the distance between them.

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.
