An electron is positioned half-way between two infinite, parallel, conducting plates that are separated by 1 cm. the plates are attached to a 100 v power supply. the top plate at y= 1.0 cm is biased at 100 volts, and the bottom plate is biased at 0.0 volts. assume that the upward y-direction is positive, and that unit vectors describing the (x, y) coordinate system are (el, e2). calculate the magnitude, and direction, of the electric field acting between the two plates. a) e (1 x 1 0e2 v/m)e2; b) e =-(1 x 10e4 v/m)e2; c) e =-(500 v/m)e2; or d) e = (1 x 1 0e6 v/m)e2.
