    Hi guys,
    I know that an electrostatic force can either be attractive or repulsive. But can it be neutral?

    A force is a vector quantity; a vector has both magnitude and direction. The notions of "attractive" and "repulsive" simply follow from the direction of the force. A "neutral" force therefore does not make any physical sense.

    The truth is that an electrostatic force is either attractive or repulsive,when opposite charges balance themselves ℓιкє in the atom it is said to be neutral,however when different types/same charges are brought close to one another the result is repulsion or attraction.
    Bodies attract each other at near distances,the convergence is inevitable. A fundamental,subtle spirit which lies hide in all gross bodies.(Newtonian gravity)

    Yes. The term neutral in EM means not electrically charged. See Neutral - Definition and More from the Free Merriam-Webster Dictionary
    The most important thing to keep in mind is that you don't know everything and nobody else does either.

    Summary: In physics, the word "neutral" is applied to charges , with "neutral" meaning "zero." "Neutral" is not, however, applied to forces.
