The diagrams below show regions of space that contain electric fields. The dotted lines represent crosssections of electric equipotential surfaces or sheets. The distance from the leftmost equipotential to the rightmost one is 20 cm in each case. An electron is placed at point S with an initial velocity of 100 m/s to the right. Rank the change in kinetic energy of the electron as it travels between points S and T in each case, from greatest to least.

An electron starts at the position shown in Figure 21-39 with an initial speed $v_0 = 5.00 imes 10^6$ m/s at $45^circ$ to the x axis. The electric field is in the $+y$ direction and has a magnitude of $3.50 imes 10^3$ N/C. The black lines in the figure are charged metal plates. On which plate and at what location will the electron strike? 10 cm 2 cm
