Electrical Fields

Electric charges are created ______.

• by gravitational forces.

• separately.

• between 2 oppositely charged objects.

• by neutrons.

How can a neutral object become charged?

• by being dipped in water

• by being stuck to the desk with tape

• by allowing gravity to work on it

• by having electrons added or removed

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 statement best describes the electric fields in the image?

• The charges are neutral.

• Both charges are negative, so the field lines are alike.

• The field lines move toward a positive charge and away from a negative charge.

• The field lines move away from a positive charge and toward a negative charge.

Which statement describes what is happening in the image at the space indicated by the green arrow?

• The field lines are repelled by like charges.

• The field lines are repelled by opposite charges.

• The field lines are attracted by the like charges.

• The field lines are attracted by the opposite charges.
