Question

question 13
which of the following most represents a field diagram of a positively charged test object?
a. the value for coulombs steadily increases.
b. the numbers in the diagram increase in value.
c. the arrows in the field diagram point away from the object.
d. there are more positive \plus\ signs than negative \minus\ signs.

Explanation:

To determine the field diagram of a positively charged test object, we recall the properties of electric field lines: electric field lines for a positive charge point away from the charge.

• Option A is incorrect as Coulomb's value (charge magnitude) doesn't "steadily increase" in a field diagram description.
• Option B is incorrect as field diagrams for charges are about field line direction, not number values increasing.
• Option C is correct because electric field lines from a positive charge radiate outward (point away from the object).
• Option D is incorrect as field diagrams for a single charged object don't involve comparing plus and minus signs in that way (it's about field line direction, not charge density comparison for a single test object).

Answer:

C. The arrows in the field diagram point away from the object.
