Question

In a particular system of units, a physical quantity can be expressed in terms of the electric charge e , electron mass m e, Planck’s constant h , and Coulomb’s constant $k=\frac{1}{4\pi\epsilon_0}$, where ε0 is the permittivity of vacuum. In terms of these physical constants, the dimension of the magnetic field is [B] = [e]α [m e]β [h]γ [k]δ. The value of α + β + γ + δ is ______.

Answer 1

The value of α + β + γ + δ is 4.
