 ===Assumptions===
-Our assumptions about the Constant B-Field, charge, and mass are essential in simplifying down the force equation. If these assumptions were not true out force could also have some time and space dependency which would make solving for and predicting the force much more dificult.

 This force would still push the particle into a circular motion (while still not affecting the particle's motion in the y-direction.) So the particle would move in an upwards spiraling path.

 So when we look at the motion of the particle from the perspective of  $+y$  going into the page, we should see a circle with radius
  $r = \frac{mv_x}{qB} = 10 \text{ m}$

+===Assumption===
+We assumed the mass was constant, and this allows for uniform circular motion in the x-z plane. If the mass were not constant then the path of the particle could look much different as the radius of curvature of the particle at any instance in time/space could change.

 However, because of the constant  $\hat{y}$  component of the velocity, this circle is actually a helix. Two perspectives show the motion below.
