Q: What do you call the space around a charged particle where the particle exerts electric force on other charged particles? Read this paragraph and choose the correct option from the provided answers: An electric field is a space around a charged particle where the particle exerts electric force on other charged particles. Because of their force fields, charged particles can exert force on each other without actually touching. Electric fields are generally represented by arrows, as you can see in the Figure below . The arrows show the direction of electric force around a positive particle and a negative particle.
