To review relationships among electric potential, electric potential energy, and force on a test charge
This problem is a review of the relationship between an electric field E? , its associated electric potential V, the electric potential energy U, and the direction of force on a test charge.
Part A
Electric field lines always begin at ___ charges (or at infinity) and end at _ charges (or at infinity). One could also say that the lines we use to represent an electric field indicate the direction in which a _ test charge would initially move when released from rest. Which of the following fills in the three missing words correctly?
(positive; negative; negative)
(positive; negative; positive)
(negative; positive; negative)
(negative; positive; 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.
