SAT Subject Physics Practice Question 466: Answer and Explanation
12. This question relates to the electric fields shown in the diagrams below, which represent two charged objects near each other in space.
Which drawing represents two unlike point charges?
A. Drawing I
B. Drawing II
C. Drawing III
D. Drawing IV
E. Drawing V
Correct Answer: E
The correct answer is (E). The explanation is the same as the explanation given in question number 10. Left with a choice between B and E, we can see the point charges in diagram E leave one point charge and enter the other point charge. That type of electric field between two point charges is produced when two unlike charges are near each other.
