Consider the motion of a charged particle of mass m and charge q in an electric field.
Consider the motion of a charged particle of mass m and charge q in an electric field (for example, in a cathode ray tube or a CRT monitor). In the absence of a magnetic field and gravity, the force exerted on the particle due to a constant electric field with strength E is given by F = qE Suppose there are two plates of length l that create a constant electric field E_0 pointing in the negative y direction, that is E= E_0y See the figure below. Furthermore, suppose that when the particle enters the plate region, it is moving in the positive x direction at a constant velocity v_0. (a) Find the position functions x(t) and y(t), assuming that the plate region starts at (x, y) = (0, 0). (b) Suppose that when the particle leaves the region, it has been vertically displaced by an amount Delta_y. What is the charge q? Assume that the plates are far enough apart so that the particle actually leaves the region. (c) Compute y(t) when we account for gravitational forces.
