A particle (mass = 5.0 g, charge = 40 mC) moves in a region of space where the electric field is uniform and is given by Ex = -2.3 N/C, Ey = Ez = 0 . If the position and velocity of the particle at t = 0 are given by x = y = z = 0 and vz = 20 m/s, vx = vy = 0, what is the distance from the origin to the particle at t = 2.0 s?
a. 60 m
b. 54 m
c. 69 m
d. 78 m
e. 3.2 m
