For one of my classes I need to implement a model of a charged particle that is giong through electric and magnetic fields.(adsbygoogle = window.adsbygoogle || []).push({});

I can assume these constants:

m=1

q=1

x(0)=0

t-scan: [0 1]

Now the questions:

1)

Simulate the constant acceleration analytic case and plot the result. Add the analytic result from the plot to demostrate the agreement. Assume, E0=[1 0 0] (also E0=E, so constant)

;;My answer: I know that it will be constant because solving for a you get q/m[E+ v' x B] and all of them are constant, but I cant plot it in Matlab, because I have NEVER used it...

2)Solve for E(x)= [5 0 0] B(x)=[0 0 20] v0=[1 1 1]. Plot the position and velocity curves. Observe and measure the ExB drift. (hint: note the vector direction of the drift) and compare it to the expected analytic result--> (which i think its like a sin/cos curve)

Please, I really need to get this done and I have tried it, but I cant get this problem to work.....

This is for problem #1

It doesnt work...and I dont have any idea why...Code (Text):

E = [1 0 0]; % define Po

t=0:.5:1; % make a vector L with 100 elements evenly spaced from 0 to 10

B=[1 0 0];

v=[0 0 0];

a2 = E+cross(v,B);

figure;

plot(t,a2);

I have NO idea for Question #2,,,so any help would be greatly appreachiated :)
