Hint:Electro-magnetic force is a fundamental force, while gravitational force is a fictitious force. Gravitational force-It possesses mass. It is an internal force. Electromagnetic force-t is exerted by a magnet. It produces magnetic waves. Gravitational force is a weaker force than Electromagnetism.

We have from then statement if ${m_1}\,,\,{m_2}$ be the two masses of the bodies, $r$ is the distance between them then, $g \propto {m_1}{m_2}$ and $g \propto \dfrac{1}{{{r^2}}}$. From here we get gravitational force is given by $g = G\dfrac{{{m_1}{m_2}}}{{{r^2}}}$, where $G$ is the Gravitational constant.
The electromagnetic force, also called the Lorentz force. Lorentz force is the force acting on a charged particle $q$that is moving with velocity $v$in an electric field $E$ and magnetic field$B$. The total electromagnetic force F acting on a charged particle is called the Lorentz force (after the Dutch physicist Hendrik A. Lorentz) and is given by
$F = qE + qv \times B$
