In a particular system of units, a physical quantity can be expressed in terms of the electric charge e, electron mass m(e), Plank’s constant h, and Coulomb’s constant k={1/[4(pi)(epislon0)]} where epislon0 is the permittivity of a vacuum . In terms of these physical constants, the dimension of the magnetic field is
[B]=[e]^(alpha) [me]^(beta) [h]^(gamma) [k]^(delta) the value of
alpha + beta + gamma + delta is________.
