3. Electron's trajectory. Consider an electron with an initial velocity of magnitude to directed at an angle below the horizontal. It enters a uniform electric field E that points vertically downward and is projected into the field. (a) Sketch the electron's trajectory within this uniform field. (b) Use your knowledge of kinematics to find the maximum vertical distance max that the electron reaches from its initial elevation. (c) Obtain the horizontal distance d it covers before it returns to its original elevation. (d) Find the mumerical values of hmax and d if E = 250 N/C, to = 8.0x105 m/s, and = 30.0°. Ignore gravitational force effects.
