Question

To review relationships among electric potential, electric potential energy, and force on a test charge

Answer 1

Answer:

positive, negative, positive

Explanation:

Electric field lines are the imaginary lines that is the path followed by an isolated unit positive charged particle in an electric field.

The direction of electric field at that point is determined by drawing the tangent at that point on the electric field line.

Part A

The electric field lines always begin at positive charges and end at negative charges.

One could also say that the lines we use to represent an electric field indicate the direction in which a positive test charge would initially move when released from rest.
