6. [15 pts. ] Two large, parallel, charged plates are separated by 35 mm as shown. The potential of the top plate is 400 V. The potential of the bottom plate is 0 V. A particle with a net charge of +2.4 mC and a mass of 5.33 x 10" kg is initially moving horizontally at a speed of 35.2 m/s close to the top plate. (A). [1 pts. ] On the picture below, use solid lines to sketch electric field lines in the region between the plates. Draw at least four electric field lines. Include arrow heads to indicate direction. (B). [/ pts. ] On the picture below, use dotted lines to sketch equipotential surfaces in the region between the plates. Draw at least four equipotential surfaces. (C). [6 pts. ] Find the initial electric potential energy, initial gravitational potential energy, and initial kinetic energy of the particle. (D). [5 pts. ] As the particle moves, its path will curve toward the bottom plate. Find the speed of the particle just before it reaches the bottom plate. Do NOT ignore gravity. (E). [2 pt. ] Explain why the horizontal component of the particle's velocity will not change as it falls toward the bottom plate.
