Is the law constant

Witryna19 wrz 2024 · In Chemistry, the Law of Definite Proportion is sometimes called Proust’s law or the law of constant composition. According to this law, a chemical compound always contains the same elements combine together in a fixed ratio by mass. WitrynaThe 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. k = 8.99 × 10 9 N ⋅ m 2 /C 2. The direction of the force is along the line joining the centers of the two objects. If the two charges are of opposite signs, Coulomb’s law gives a negative result.
