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.

The Affect of Electric fields surrounding particles become stronger the _______________ they are from each other.

• Farther

• Closer

What does it mean when the electric field lines are close together?

• the field is positive

• the field is negative

• The field is strong
