What is causing the plague in Thebes and how can it be fixed? Electrostatic charge arises from a build-up or deficit of free electrons in a material, which can exert an attractive force on oppositely charged objects, or a repulsive force on similarly charged objects. On the other hand, Material C repels Material A. Most objects are electrically neutral, which means that they have an equal number of positive and negative charges. positively charged having a positive charge; protons are positive electropositive, positive.
