electric field diagrams

What charge is used as a "test charge"

• A small negative charge.

• A small positive charge.

• A small neutral object.

The electric force is 

• stronger when closer to the source charge.

• weaker when closer to the source charge.

• always the same strength.

The electric field around a POSITIVE charge points 

• OUT (away) from the positive charge.

• IN (towards) the positive charge.

Which of the following best describes the relationship between the how close electric field lines are drawn?

• Field lines close together are stronger than field lines further apart.

• Field lines further apart are stronger than field lines closer together.

• How close the field lines are drawn makes no difference on the strength of the electric field.

WHY does the electric field line point inward (toward the negative charge)?

• The electric field points inward (toward the negative charge) because the test charge is negative and feels a force inward (toward the negative charge 

• The electric field points inward (toward the negative charge) because the test charge is positive and feels a force inward (toward the negative charge).

• The electric field points inward (toward the negative charge) because the test charge is neutral and feels a force inward (toward the negative charge).

Where is the net force zero?

• very far away from 2 charges 

• Midway between two of the same charge

What will the Electric Field look like?

• going down from positive to negative

• going up from negative to positive
