Electric Field

At which point is the electric field the strongest

• A
• B
• C
• D

At which point is the electric field the weakest?

• A because it is the furthest away
• A because the field lines are further apart
• C because the field lines are further apart
• C  because it is the furthest away

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

• +,+
• +,-
• -,+
• -,-

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

Which diagram correctly shows the field lines between two like charges?

• A

• B

• Both

• Neither

A region of influence surrounding an object is best defined as:

• An electric field
• A field
• A force
• A gravitational field

When an object gains electrons it becomes __________

• Neutral

• Positively charged

• Negatively charged

An atom of oxygen has 8 protons and 10 electrons, this means the atom is ____________

• positively charged because it has excess electrons

• negatively charged because it has excess electrons

• positively charged because it has a deficiency of electrons

• negatively charged because it has a deficiency of electrons

The electrical force between charges is strongest when the charges are

• close together
• far apart
•  the electric force is constant everywhere.
• there is no pattern
