What is the difference between an electric field and gravitational field? [duplicate]
Since the electrostatic field and the Newtonian gravitational field share a similar form: proportional to
$$
\frac{1}{r^2}
$$
Is there any qualitative difference between motions under the ...

Is Newton's universal gravitational constant the inverse of permittivity of mass in vacuum?
Is it possible to consider Newton's universal gravitational constant, $G$, as inverse of vacuum permittivity of mass?
$$\epsilon_m=\frac {1}{4\pi G}$$
if so, then vacuum permeability of mass will be:...
