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.
