Electric Potential and Potential Energy A particle with charge 3.20x10'19 C is placed on the xaxis in a region where the electric potential due to other charges increases in the +Xdirection but does not change in the y or z direction. V Part A 1of19 I Review | Constants The particle, initially at rest, is acted upon only by the electric force and moves from point a to point b along the xaxis, increasing its kinetic energy by 9.60x10'19 J . In what direction and through what potential difference Vb Va does the particle move? D View Available Hint(s) O O 0000 The particle moves to the left through a potential difference of Vb Va = 3.00 V . The particle moves to the left through a potential difference of Vb Va = -3.00 V The particle moves to the right through a potential difference of V}, V; = 3.00 V . The particle moves to the right through a potential difference of W, V; = -3.00 V . The particle moves to the left through a potential difference of Vb Va = 30.0 V . The particle moves to the right through a potential difference of V}, V; = -30.0 V . > Part B If the particle moves from point b to point c in the y direction, what is the change in its potential energy, Uc - Ub?
