An electron is initially moving to the right at 2.50 x 106 m/s. It enters a region of space where there is a constant electric field of magnitude 0.125 mN/C and directed upward. (a) In which direction will the electron accelerate? Explain. (b) What will be the shape of the electron's trajectory? (c) During a certain amount of time in the electric field, the electron moves 25.0 cm to the right. How far does it move vertically during this time?

An electron moves along the trajectory from i to f in as shown in
the figure to the right.
(a) Does the electric potential energy increase, decrease, or stay
the same? Explain.
(b) To trace out a trajectory like this, the electron must have
a nonzero initial velocity. What is its direction (Use a coordinate system where xˆ points towards the right, yˆ points
toward the top of the page and zˆ points out of the page).
(c) Is the electron’s speed at f greater than, less than, or equal
to its speed at i? Explain
