Atotal charge Q is uniformly distributed around a ring-shaped conductor with radius a . Acharge q is located at a distance x from the center of the ring .
F=(1/(4*pi*e0)) * (q*Q*x)/((x^2+a^2)^(3/2)) e0=8.85*10^(-12) (C^2/N*m^2) q=Q=2*10^(-5) C a=0.9 m x=? where the force is a ma...

Develop contour and surface plots in MATLAB. Minimize the potential energy function in order to determine the equilibrium displacements x1 and x2 given the forcing function F = 100 N, and the parameter ka = 100/6 and kb = 15 N/m.
PE=0.5*ka*x1^2+0.5*kb*x2^2-F*(x1+x2)
