An alpha particle (a helium nucleus) is traveling along thepositive x-axis at 1175 m/s when it enters a cylindrical tube ofradius 0.400 m centered onthe x-axis. Inside the tube is a uniform electricfield of 5.00 10-4 N/C pointing in thenegative y-direction. How far does the particle travel before hitting the tube wall? Neglect any gravitationalforces.Note: mα = 6.64 10-27 kg; qα =2e.
