Electric Fields Review

Consider the electric field lines shown in the diagram below. From the diagram, it is apparent that object A is ____ and object B is ____.

• +,+
• +,-
• -,+
• -,-

Consider the electric field lines drawn at the right for a configuration of two charges. Several locations are labeled on the diagram. Which of these shows the ranking in order of weakest to strongest correctly

• A, E, C
• D, E, C
• D, B, A
• A, D, B

Q_A and Q_B are two charges creating an electric field. Based on the electric field lines, we can conclude

• Q_A and Q_B are both positive
• Q_A and Q_B are both negative
• Q_A is positive and Q_B is negative
• Q_A is negative and Q_B is positive

Based on the arrangement of the electric field lines in the diagram, what are the charges?

• both charges are the same

• the charges are opposite

• they are neutral; no charge
