The figure shows a proton p and an electron e that are at rest on a line in the plane of the page. They are between two large uncharged parallel plates (not shown). Assume the particles are far apart so that their mutual gravitational and electrostatic forces are negligible. An electric field directed toward the top of the page is now established between the plates. Which of the following describes the velocity of the center of mass of the particles before either of them hits one of the plates? Toward the top of the page and increasing Toward the top of the page and constant Toward the bottom of the page and increasing Zero
