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)__
