Electric Field Line Concepts

EANDM-1Q1FBD

Electric field lines are used to represent the vector electric field around point charges and charged objects.

Which of the following statements are true about electric field lines. Select ALL that apply.

A

Electric field lines cannot cross.

B

Lines of electric field only originate from positive charges.

C

Field lines point in the direction of the force the electric field creates on an electron.

D

The strength of the electric field is greater in regions where the field lines are closer together.

E

In an electric-field-line drawing with many point charges, the number of field lines originating or terminating on each charge is proportional to the charge. That is, bigger charges have proportionally more field lines.

F

The true strength of an electric field at any point can be determined from an electric field representation.
