Which of the following terms represents a map of an electric field indicating the direction of force experienced by a positive charge?

The term that represents a map of an electric field indicating the direction of force experienced by a positive charge is electric field lines. These lines visually depict how an electric field behaves in space.

Electric field lines start on positive charges and end on negative charges, illustrating the path a positive test charge would follow if placed in the field. The density of these lines indicates the strength of the electric field—closer lines represent a stronger field, while lines that are further apart indicate a weaker field. Moreover, at any point along these lines, the direction of the line indicates the direction of the force that a positive charge would experience if placed in that field.

This concept is essential for understanding how charges interact in an electric field, as well as for visualizing the effects of various charge configurations on the surrounding space.
