As is well known, the Coulombic force between point charges q1 and q2 is given by
Fc=(1/4 pi epsilon0)(q1q2/r^2) (1)
And as is well known also, the gravitational force between point masses m1 and m2 is given by
where epsilon0 is the dielectric constant, G the gravitational constant and r the distance between the point charges or point masses.
Both of equation (1) and (2) are mathematically equivalent, that is, they are proportional to the inverse squared distance.
Since the dimension of both of them is [Newton], the dimension of the constant parts are also identical.
[q1q2/4 pi epsilon]=[Gm1m2] (3)
Since in the electromagnetism the forces are governed by the Maxwell's equations or Lorentz force, one might be seduced to think about a gravitational version of the Maxwell's equations. Are such equations known or do they exist?
The most intriguing thing is the similar function of the products q1q2 and m1m2. Do they behave the similar methematical play in each mechanism? What are the electric charge and mass at all? What should be asked should be asked many times until we can give a satisfactory answer. What will your speculation about this be, Sirs?

The problem is this.
According to Einstein, mass is equivalent to energy. That is
That is, mass is proportional to energy.
Therefore we cannot but imagine that a mathematical product of energy can generates gravitational force.
Since m1 is energy and m2 is also energy, then the product of m1 and m2 means energy squared, and this energy squared quantity becomes gravitational force.
In much the similar way, electric charges q1 and q2 can generate Coulombic force. By reverse inference, the electric charge q1 and q2 must be proportional to energy.
The conclusion is this. The electric charge might be equivalent to energy.
How do you think, Sirs?
