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 = 0.78 m in the x-direction. The proton leaves the field having a velocity vector (Vx, Vy) = (2.3 X 105 m/s, 1.7 X 105 m/s). y B V h 1) What is v, the magnitude of the velocity of the proton as it entered the region containing the magnetic field? m/s Submit 2) What is R, the radius of curvature of the motion of the proton while it is in the region containing the magnetic field? m Submit 3) What is h, the y co-ordinate of the proton as it leaves the region conating the magnetic field? m Submit 4) What is B, the z-component of the magnetic field? Note that B is a signed number. T Submit 5) If the incident velocity v were increased, how would h and 0 change, if at all? 00000 h and 0 would both increase Oh and 0 would both decrease h would increase and 0 would decrease h would decrease and 0 would increase Neither h nor e would change +
