A proton is initially at rest and moves through three different regions as shown in the figure. In region 1, the proton accelerates across a potential difference of 3330 V. In region 2, there is a magnetic field of 1.20 T pointing out of the page and an electric field pointing perpendicular to the magnetic field and perpendicular to the proton's velocity. Finally, in region 3, there is no electric field, but just a 1.20-T magnetic field pointing out of the page.
(a) What is the speed of the proton as it leaves region 1 and enters region 2?
(b) If the proton travels in a straight line through region 2, what is the magnitude and direction of the electric field?
(c) In region 3, will the proton follow path 1 or 2?
(d) What will be the radius of the circular path the proton travels in region 3?
