Webb12 sep. 2024 · For convenience, we often define a Coulomb’s constant: ke = 1 4πϵ0 = 8.99 × 109N ⋅ m2 C2. Example 5.4.1: The Force on the Electron in Hydrogen A hydrogen atom consists of a single proton and a single electron. The proton has a charge of + e and the electron has − e. This law states that a specified physical quantity is inversely proportional to the square of the distance. In some modern systems of units, the Coulomb constant ke has an exact numeric value; in Gaussian units ke = 1, in Heaviside–Lorentz units (also called rationalized) ke = 1 4π. Visa mer The Coulomb constant, the electric force constant, or the electrostatic constant (denoted ke, k or K) is a proportionality constant in electrostatics equations. In SI base units it is equal to 8.9875517923(14)×10 … Visa mer The Coulomb constant is used in many electric equations, although it is frequently expressed as the following product of the vacuum permittivity constant: Visa mer The Coulomb constant is the constant of proportionality in Coulomb's law, $${\displaystyle \mathbf {F} =k_{\text{e}}{\frac {Qq}{r^{2}}}\mathbf {\hat {e}} _{r}}$$ where êr is a unit vector in the r-direction.

Now, we need to rework the equation so that we are calculating for the missing metric, which is the spring constant, or k. Looking only at the magnitudes and therefore omitting the negative sign, you get.
