Question

question 14
which of the following most represents a field diagram of a negatively charged test object?
a. the value for coulombs steadily decreases.
b. the numbers in the diagram decrease in value.
c. the arrows in the field diagram point toward the object.
d. there are more negative \minus\ signs than positive \plus\ signs.

Explanation:

To determine the field diagram of a negatively charged object, we recall electric field concepts: Electric field lines for a negative charge point toward the charge (since electric field direction is the force on a positive test charge, and a negative charge attracts positive charges, so field lines converge to it).

• Option A: Coulomb's value decreasing isn't about field diagram arrows/direction.
• Option B: Numbers decreasing in diagram doesn't relate to field direction for a negative charge.
• Option C: Arrows toward the object matches the electric field direction for a negative charge (field lines point toward negative charges).
• Option D: More minus signs than plus signs is about charge quantity, not field diagram representation.

Answer:

C. The arrows in the field diagram point toward the object.
