That can be the following:
Use two empty to represent the charge locations, and add parameters for the charge values.
Define a grid and instanciate an arrow on its points.
Align the arrows to the force field of the two charges.
The force field of a charge is the following node group:
Which calculate the force with the charge value and its magnitude relative to 1 / distance²
of the charge.
