Physics k constant coulomb's law
WebbCoulomb’s law is a law of physics that states when two or more electrically charged objects are close enough to each other, they exert a force on each other. The magnitude of this force is proportional to the net charge of the particles and inversely proportional to the square of the distance between the particles under study. WebbThe constant of proportionality k is called Coulomb’s constant. In SI units, the constant k has the value k = 8.99 × 10 9 N ⋅ m 2 /C 2. The direction of the force is along the line …
