The exponent of charge variables in physical law must be unity in order for them to apply to distributed charges |
---|
Let Z be a physical charge such as gravitational mass or electric charge for some physical body, that determines some variable E in the form
where α and β are parameters.
Suppose now that the body is divided up into m equal proportions. The amount per portion is then α(Z/m)β and the total is
and therefore
Thus only the case of β equal to 1 is meaningful physically.
