An electron moves along the trajectory from i to f in as shown inthe figure to the right.(a) Does the electric potential energy increase, decrease, or staythe same? Explain.(b) To trace out a trajectory like this, the electron must havea nonzero initial velocity. What is its direction (Use a coordinate system where xˆ points towards the right, yˆ pointstoward 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 equalto its speed at i? Explain
