THE QUESTION I AM SHARING WITH YOU IS THE QUESTION
FROM THE SUBJECT ELECTROMAGNETICS IN THIS QUESTION WE HAVE TO USE
MATLAB PLEASE COMMENT EACH STEP AND DO YOUR BEST TO SLOVE
IT
Question2: [5 marks]
Use MATLAB to write a generic program to find “E” at point P (x1,
y1, z1) in free space due to the following charge distributions:
point charge, A nC, at point P (x2, y2, z2) in free space; uniform
line charge density, B nC/m, at x = t, y = t1; uniform surface
charge density, C nC/m2 at x = t2.
Where A, B, C, x1, y1, z1 x2, y2, z2, t, t1& t2 can take any
arbitrary value from real numbers
If you have any doubts , ask me in comment section.
Let's take this example :
Code :

RAW_CODE :
A = input('A :'); %taking inputs from user
B = input('B :');
C = input('C :');
x1 = input('x1 :');
y1 = input('y1 :');
z1 = input('z1 :');
x2 = input('x2 :');
y2 = input('y2 :');
z2 = input('z2 :');
t = input('t :');
t1 = input('t1 :');
t2 = input('t2 :');
point = [x1,y1,z1];
%point charge
q = A*10^-9; %given values
epsi = 8.85*10^-12;
p = [x2,y2,z2];
r_r0 = point - p;
magni = sum(r_r0.^2)^1.5; %calculating |r-r0|^3
Eq = q/(4*pi*epsi*magni) .*r_r0; %given formula
fprintf('Eq = %fax %fay %faz c/m^2\n',Eq(1),Eq(2),Eq(3));
%printing
%line charge
pl = B*10^-9;
pp = [t,t1,z1];
a = point - pp;
b = sqrt(sum(a.^2)); %calculating |[4,0,3]-0,2,3]|
ap = a./b;
p = b;
El = pl/(2*pi*epsi*p) .*ap; %given formula
fprintf('El = %fax %fay +%faz c/m^2\n',El(1),El(2),El(3));
%surface charge
ps = C*10^-9;
Evol = ps/(2*epsi); %given formula
fprintf('Ev = %fax\n',Evol);
Ev = [Evol,0,0];
%total charge
E = Eq .+ El .+ Ev;
%printing with x,y,z components

using matlab thank you 3 MARKS QUESTION 3 Background The van der Pol equation is a 2nd-order ODE that describes self-sustaining oscillations in which energy is withdrawn from large oscillations and fed into the small oscillations. This equation typically models electronic circuits containing vacuum tubes. The van der Pol equation is: dt2 dt where y represents the position coordinate, t is time, and u is a damping coefficient The 2nd-order ODE can be solved as a set of 1st-order ODEs,...
