Electric Potential Multiple Choice Problems NJCTL
We define the electric potential as the potential energy of a positive test charge divided by the charge q0 of the test charge. 0 U V q = It is by definition a scalar quantity, not a vector like the electric field. The SI unit of electric potential is the Volt (V) which is 1 Joule/Coulomb. The units of the electric field, which are N/C, can also be written as V/m (discussed later). Changes in... (A) are parallel to the electric force on a test charge placed at that location. (B) are to perpendicular lines (surfaces) of constant electric potential at that location. (C) never cross.

59 E The electrical potential energy of a pair of charges is given by kq1q2/r, where r is the distance between the charges. Therefore, the electrical potential energy of the pair of charges +Q and +Q will be greatest when the distance between them is the smallest. Of the five diagrams given, the charges are closest together in diagram E. 60 A By the principle of superposition, the total pdf signer 8.7 keygen View Test Prep - Practice Quiz 3.pdf from PHYS 2200 at California State University Los Angeles.
