. A pair of parallel plates is given equal and opposite surface charge density a = 4.2 [112me A sphere of charge E1 is placed between plates and released from rest. A} Write down the vector form of the electric field between the plates using unit Iuectors {3 points] s\": .m. B} If the sphere moves a distance d = 0.11 meters after heingr released, calculate the work done he on the sphere {5 points} IE] At the end of this motion, the sphere is moving at 1.1 mils. Calculate the charge {in Coulombs} on the sphere assuming its mass is ill kg [8 points] V + + + d Q + + + + + X + * Between two conducting plates of length L = 9.85 cm a uniform electric field of magnitude 1.95 x 10' N/C has been setup. The lower plate has positive charge on it and the upper plate has negative charge on it. The two plates are separated by a distance d = 1.95 cm. An electron is shot between the plates from the lower right edge with an initial velocity vo = 5.8 x 10* m/s at an angle of 40 degrees with respect to the horizontal. . A) Will the electron strike one of the plates, and if so which one (top or bottom)? . B) Calculate the horizontal position where the electron will cross the vertical plane y = 0 . C) Calculate the velocity (magnitude and direction) the electron has when it crosses the vertical plane y = 0
