- An alpha particle (a helium nucleus) is traveling along the positive x-axis at 1200 m/s when it enters a cylindrical tube of radius 0.400 cm centered on the x-axis. Inside the tube is a uniform electric field of 5.50 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.
