A Particle (Mass = 5

question 26

Multiple Choice

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 E_x = −5.5 N/C, E_y = E_z = 0. If the position and velocity of the particle at t = 0 are given by x = y = z = 0 and v_x = 50 m/s, v_y = v_z = 0, what is the distance from the origin to the particle at t = 2.0 s?

• A) 60 m
• B) 28 m
• C) 44 m
• D) 12 m
• E) 88 m
