What is the fundamental difference between the vector nature of electrostatic force and the vector nature of gravitational force?

Reps will be given accordingly.

There are no negative gravitational charges (no negative mass) but there are both positive and negative electric charges. So you'll never have opposing gravitational vectors.

more specifically -
vector wise we only have gravitational-PULL i.e.
Gravitational force between 2 objects is always attractive in nature.
Electrostatic force between 2 objects can be attractive or repulsive.
(Due to the charges)

its like we got planets and we got magnets, can't live on a magnet and you can't find the number to dominos on a planet, cause you can't stick one to your friderator....

those other two brahs already posted what i was gonna say...
