The electric force calculator simplifies the complex interactions between charged particles into understandable and quantifiable terms. It provides a means to calculate the magnitude of the force exerted between two charged objects. Such calculations are not only foundational in physics education but also essential in designing electrical devices and understanding natural phenomena.
Formula of Electric Force Calculator
To ground our understanding, let’s look at the core of the calculator’s function, represented by the formula:
F = k * q1 * q2 / r²
where:
Fis the electric force (measure in Newtons, N)kis the Coulomb constant (approximately equal to 8.988 x 10^9 N * m²/C²)q1andq2are the charges of the two particles (measured in Coulombs, C)ris the distance between the centers of the two particles (measure in meters, m)
This formula encapsulates the essence of Coulomb’s law, providing a direct route to understanding the invisible forces at play between charged particles.

Most Common FAQs
A1: Yes, electric force can be both attractive and repulsive, depending on the charges of the interacting particles. Like charges repel, while opposite charges attract.
A2: Electric force decreases with the square of the distance between the charged particles. Doubling the distance reduces the force by a factor of four.
