A particle with charge 8.00×10^(-19) C is placed on the x-axis in a region where the electric potential due to other charges increases in the +x direction but does not change in the y or z direction.
A. 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 4.80×10^(-19) 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) = 0.600 V.
b. The particle moves to the left through a potential difference of (Vb - Va) = -0.600 V.
c. The particle moves to the right through a potential difference of (Vb - Va) = 0.600 V.
d. The particle moves to the right through a potential difference of (Vb - Va) = -0.600 V.
e. The particle moves to the left through a potential difference of (Vb - Va) = 6.00 V.
f. The particle moves to the right through a potential difference of (Vb - Va) = -6.00 V.
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)?
