To calculate the force between two charged particles, we use the Coulomb's law. Follow these easy steps to find the result:
Find the charges q1 and q2 of the particles in coulombs, and multiply them.
Multiply the result of step 1. by the constant ke = 8.988E9 (N × m²)/C².
Divide the result by the square of the distance between the particles.
The result is the force (attractive if negative in sign, repulsive if positive) acting between the charged particles. Read more
