What is defined as the space around a charged object in which another charged object experiences an electric force?

The concept being described is the electric field, which is indeed associated with charged objects. An electric field is defined as the region surrounding a charged object where another charged object would experience an electric force. This field represents the influence that a charge exerts on other charges in its vicinity and is characterized by both magnitude and direction.

The strength of the electric field at a point is determined by the amount of force that a unit charge would experience if placed at that location. It can be visually represented by field lines that radiate outward from positive charges and inward toward negative charges. This helps illustrate both the direction of the field and its strength, with denser lines indicating stronger fields.

Other options—like magnetic fields, electric potential, and electromagnetic fields—do not fit the definition provided as precisely. A magnetic field pertains to the influence of moving charges or magnets, an electric potential relates to the work done per unit charge in bringing a charge from infinity to a point in the field, and an electromagnetic field is a combination of both electric and magnetic fields interacting together. However, the specific space where a charged object exerts its influence on other charges is best defined by the electric field.
