(a) Use a computer program to plot the cycloid curve in the xy plane, given the parametric equations:
x(θ) = θ - sin θ
y(θ) = 1 - cosθ
(b) For a charge q moving in crossed (i.e., orthogonal) E and B fields, starting from rest at the origin, plot the kinetic energy as a function of time.
I have plotted it in MATLAB. Here is the code
clc;clear;
% patameter time or theta
t=[0:0.1:15];
% cycloid equations
x=t-sin(t);
y=1-cos(t);
% kinetic energy and time relation
KE=(sin(t./2)).^2;
% plot for cycloid
subplot(2,1,1);
plot(x,y,'r')
xlabel('x-axis')
ylabel('y-axis')
% plot for Kinetic energy
subplot(2,1,2);
plot(t,KE,'b')
xlabel('t (or \theta)')
ylabel('K.E.')
Here is the screenshot

A frictionless wire is bent into the shape of a cycloid curve, with coordinates given by the parametric equations ? = ?(? + sin ?), ? = ?(1 − cos ?), for −? < ? < ?. The x axis is horizontal, and y is vertically upwards. A bead of mass m slides freely on the wire. Show that the distance s, measured along the wire from the origin, is given by ? = 4? sin. Write out the potential...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
