Question

what is the indicator of how strong an electric field is in an electric field diagram?
a. number values
b. value of coulombs
c. space between arrows
d. number of plus or minus signs

Explanation:

In an electric field diagram, the strength of the electric field is indicated by the spacing between the electric field lines (represented by arrows here). Closer arrows (less space between them) mean a stronger electric field, and wider spacing means a weaker field. Number values (A) aren't typically used in basic field diagrams, coulombs (B) measure charge, and the number of plus/minus signs (D) relates to charge sources, not field strength.

Answer:

C. space between arrows
