Question 1

A particle (m = 50 g, q = 5.0 μC) is released from rest when it is 50 cm from a second particle (Q = −20 μC). Determine the magnitude of the initial acceleration of the 50-g particle.

◦
54 m/s2

◦
90 m/s2

◦
72 m/s2

◦
65 m/s2

◦
36 m/s2


Question 2

A particle (mass = 4.0 g, charge = 80 mC) moves in a region of space where the electric field is uniform and is given by Ex = −2.5 N/C, Ey = Ez = 0. If the velocity of the particle at t = 0 is given by vx = 80 m/s, vy = vz = 0, what is the speed of the particle at t = 2.0 s?

◦
40 m/s

◦
20 m/s

◦
60 m/s

◦
80 m/s

◦
180 m/s
