A small object with mass m, charge q, and initial speed v0 =
6.00×103 m/s is projected into a uniform electric field
between two parallel metal plates of length 26.0 cm (Figure 1). The
electric field between the plates is directed downward and has
magnitude E = 700 N/C . Assume that the field is zero outside the
region between the plates. The separation between the plates is
large enough for the object to pass between the plates without
hitting...
