This diagram describes the mechanisms of Coulomb's law in Physics/Electromagnetism; two equal (like) point charges repel each other, and two opposite charges attract each other, with an electrostatic force F which is directly proportional to the product of the magnitudes of each charge and inversely proportional to the square of the distance r between the charges. Regardless of attraction, repulsion, charges or distance, the magnitudes of the forces, |F| (absolute value), will always be equal. Ke is Coulomb's constant.

An overbar can be used to get F̄ but F⃑ or F⃗ would be better.
Most fonts do not have the latter two, and even if they do, the metrics may not work.
Liberation Sans has them, but they mostly overlap the character and become almost invisible.
Math typesetting conventions vary by country.
Bold Roman (bold says vector).
Bold Italic (bold says vector, and italic says variable).
Regular Italic with decoration (hat or arrow to distinguish vector variable from ordinary variable).
There may be Bold Roman/Italic with hat to show unit vector, but bold with arrow decoration seems uncommon.
