An alpha particle (a helium nucleus) is traveling along the positive x-axis at 1100 m/s when it enters a cylindrical tube of radius 0.600 cm centered on the x-axis. Inside the tube is a uniform electric field of 4.00  10-4 N/C pointing in the negative y-direction. How far does the particle travel before hitting the tube wall? Neglect any gravitational forces. Note: m? = 6.64  10-27 kg; q? = 2e.  m

The velocity of a particle (m= 10 mg, q= -4 microC) at a t=0 is 20m/s in the positive x-direction. If the particle moves in a uniform electric field of 20 N/C in the positive x-direction, what is the particle's velocity (in m/s) at t = 11.9 s ?

Problem 12:   A simple and common technique for accelerating electrons is shown in the figure, which depicts a uniform electric field between two plates. Electrons are released, usually from a hot filament, near the negative plate, and there is a small hole in the positive plate that allows the electrons to pass through. E = 2.4 × 104 N/C Calculate the horizontal component of the electron's acceleration if the field strength is 2.4 × 104 N/C. Express your answer in meters per second squared, and assume the electric field is pointing in the negative x-direction as shown in the figure.
