Homework Help: Physics

Posted by Kevin on Tuesday, February 5, 2013 at 5:40am.

An electron is projected with an initial speed of (1.6x10^6 m/s) into the uniform field between two parallel plates. Assume that the field between the plates is uniform and directed vertically downward, and that the field outside the plates is zero. The electron enters the field at a point midway between the plates

a) If the electron just misses the upper plate as it emerges from the field, find the magnitude of the electric field.

b) Suppose that the electron is replaced by a proton with the same initial speed. Would the proton hit one of the plates? If the proton does not hit one of the plates, what is the magnitude and direction of its vertical displacement as it exits the region between the plates.

c) Compare the paths traveled by the electron and the proton and explain the differences.
