1. The problem statement, all variables and given/known data An alpha particle (a helium nucleus) is traveling along the positive x-axis at 1425 m/s when it enters a cylindrical tube of radius 0.700 m centered on the x-axis. Inside the tube is a uniform electric field of 5.00x10-4 N/C pointing in the negative y-direction. How far does the particle travel before hitting the tube wall? Neglect any gravitational forces. Note: mα = 6.64x10-27 kg; qα = 2e. 2. Relevant equations Eq=F d(delta)y=v(int)yt + 1/2at^2 d(delta)x=v(int)xt 3. The attempt at a solution (5x10-4)(2)(1.6x10-19) = F = 1.6 x 10-22 F=ma (1.6 x 10-22)/(6.67 x 10-27) = a = -2.41 x 10-4m/s^2 d(delta)y=v(int)yt + 1/2at^2 -.7= 0 + (.5)(-2.41 x 10-4)(t^2) t= .007622s d(delta)x=v(int)xt d(x)= (1425)(.007622s)= 10.86 m I'm not sure what I did wrong, but I checked my math twice so I guess it must be something with the process that I took. Please let me know if you can help! Thanks!
