A proton (q= 1.6 X 10^-19 C, m =1.67 X 10^-27 kg moving with constant velocity enters a region containing a constant magnetic field that is directed along the z-axis at (x,y)= (0,0) as shown. The magnetic field extends for a distance D= 0.45m in the x-direction. The proton leaves the field having a velocity vector (vx,vy) = (3.4 X 10^5m/s, 2.7 X 10^5 m/s)
1) What is the magnitude of the velocity of the proton as it enters the region containing the magnetic field?
2) What is R, the radius of the curvature of the motion of the proton while it is in the region containing the magnetic field?
3) What is the y-coordinate of the proto as it leaves the region containing the magnetic field?
4) What is Bz, the z-component of the magnetic field?
