PHYSICS 4B Chapter 21 21.17 Three point charges are arranged along the x-axis. Charge q 1 = +3.00 μ C is at the origin, and charge q 2 = -5.00 μ C is at x = 0.200 m. Charge q 3 = -8.00 μ C. Where is q 3 located if the net force on q 1 is 7.00 N in the –x-direction? 21.31 An electron is projected with an initial speed v 0 = 1.60 × 10 6 m/s into the uniform field between the parallel plates in Fig. 21.32. Assume that the field between the plates is uniform and directed vertically downward, and that the field outside the plates is zero. The electron enters the field at a point midway between the plates. a) If the electron just misses the upper plate as it emerges from the field, find the magnitude of the electric field. b) Suppose that in Fig. 21.32 the electron is replaced by a proton with the same initial speed v 0 . Would the proton hit one of the plates? If the proton would not hit one of the plates, what would be the magnitude and direction of its vertical displacement as it exits the region between
