The particle, initially at rest, is acted upon only by the electric force and moves from point a to point b along the x-axis, increasing its kinetic energy by 1.44ã—10^(−18) j. in what direction and through what potential difference vb-va does the particle move? a. the particle moves to the left through a potential difference of vb-va = 0.500 v. b. the particle moves to the left through a potential difference of vb-va = -0.500 vc. the particle moves to the right through a potential difference of vb-va = 0.500 v. d. the particle moves to the right through a potential difference of vb-va = -0.500 v. e. the particle moves to the left through a potential difference of vb-va = 5.00 v. f. the particle moves to the right through a potential difference of vb-va = -5.00 v.
