v=7.488, 10:19 7. (20 points) A proton is initially at rest and moves through three different regions as shown in the figure. In the region 1, the proton accelerates across a potential difference of 2630 V. In region 2, there is a magnetic field of 1.20 T pointing out of the page and an electric field (not shown) 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. In regions 1 and 2 the proton moves to the right in a straight line. In region 3 the proton moves in a circular motion. 18.65 x 10-th mils x Region 1 Region 2 Region 3 a) What is the speed of the proton as it leaves region 1 and enters region 2? -20 b) What is the magnitude of the electric field in region 2? c) In region 3, the proton will curve upwards, downwards, out of the page, or into the page?
