What does the electric field around a neutral object look like?

• Lines pointing inwards

• Lines pointing outwards

• Lines that criss cross

• There are no lines at all

Which of the following is NOT one of the rules about drawing electric field lines?

• Lines enter negative

• Lines exit positive

• Lines never cross

• Lines close together indicate stronger forces.

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.
