A proton travels in the plane of the screen, as shown, at a constant speed through two separate shaded regions of magnetic field, B1 and B2. The magnetic field in each shaded region is perpendicular to the plane of the screen and uniform in magnitude and direction. The magnetic field is zero outside of the shaded regions. Which statements are correct based on the information shown about the trajectory of the proton? I. B1 points out of the page. II. The magnitude of B1 is greater than B2 . III. The proton spends more time in region 1 than region 2.
