Four particles enter a region of uniform magnetic field with velocities perpendicular to magnetic field lines. The particles have the following masses and charges: 1 : charge q; velocity v and mass m
2: charge 29 velocity 2v and mass 2m
3: charge q: velocity 3v, mass m/2
4: charge 2q: velocity 30, mass 2m
Rank the radii of theirs paths for these particles, largest to smallest

Find the steady-state temperature at the center of the plate = /2, = /2) for sums of w from n=1 to n=19 (only odd values). find the value of n for which the change in /2, /2) is less than 1% from the value at the previous n. at this point, we consider the solution converged. does the value of the temperature at the center seem reasonable? in this part, the values of x and y are constant scalar values. you should produce a plot of the value of n on the horizontal and the estimate of the temperature at the center of the plate on the vertical. b. using the value of n (or larger) that resulted in convergence in part (a), create a contourf plot of the temperature distribution across the entire plate. use enough spatial subdivisions to create a useful plot. comment on the results. hint: you need to determine what “x” and “y” values to use to make your t matrix. i recommend using a different number of x and y values. use enough x and y values so that the plot is “smooth”.
