The expression Φ(x, h)-(1-2xh + h2)-1/2 where |hl < 1 is the generating function for Legendre polynomials. φ(x, h) can be expressed as a sum of Legendre polynomials The function (x, h) = Po(x) + h...
Physics 102 Extra Credit Legendre Polynomials Problem The following problem is worth 5 ertra credit points! Consider a disk of radius R carrying charge q (un formly distributed) and lying in the ry plane as seen in the diagram. We want to determine the potential V(r,0) everywhere outside the disk, for r R (because of the azimuthal symmetry the potential doesnt depend on φ). We have seen earlier that the potential along the z-axis (when 0-0) is gr R2 V(ro-ro...
3. (a) Consider two vectors x and x' with x >x'). Use the generating function for the Legendre polynomial and the addition theorem for spherical harmonics to show: - 47 x'' 1 x - x' 2221 + 1 Yom (0.6) I=0 m=-, 21 +1xl+"Im(0, (b) Use this formula to compute the potential at point x due to a line of charge of uniform density extending on the y-axis from y = 0 to y = L, where L < x.
If you were to use a trial function of the form φ(x):: (1 + cax 2)r"r/2, where α (kμ/h2)1/2 and c is a variational parameter, to calculate the ground-state energy of a harmonic oscillator, what do you think the value ofc will come out to be? Why? 8-6.
1. The two-point forward difference quotient with error term is given by where ξ e ll, l + hl. In class we showed an additional error term appears to due to computer rounding error, e(r). Denoting (z) f(x) +e(x) as what the com- puter stores, and supposing f"(x)M and e() e where e, M are constants, we obtained an upper bound for the error between f(r) and the computed forward difference quotient 2c h Find the minimum value of the...
2. Potentials and a Conducting Surface The electric potential outside of a solid spherical conductor of radius R is found to be V(r, 9) = -E, cose (--) where E, is a constant and r and 0 are the spherical radial and polar angle coordinates, respectively. This electric potential is due to the charges on the conductor and charges outside of the conductor 1. Find an expression for the electric field inside the spherical conductor. 2. Find an expression for...

FAO Figure 1 2. A thin wire of length L has a uniform charge density +1.A cylindrical Gaussian surface of radius d is drawn with the wire along its central axis, as shown above. Point P is located at the center of one end of the cylinder, a distance d from the end of the wire. Point Q is on the edge of the cylinder directly above the center of the wire, as shown above. A student says, "Gauss's law...
I was able to get about half way through 1 but don't know how to get to cos(cos(theta)). If I can get a step by step force each part that'd be most helpful. General Physics II, Phys 2331, Exam Prep 1) Two equal opposite charges are separated from each other with distance d create an electric dipole moment aj Find the electric potential at point A at distance r from the midpoint of two charges (see Fig 1). b) Suppose...
Please Answer only (e) (f) (g) and (h) Other have been answered ! continuous object using integrals. Consider a thin, charged rod of length, L It lies along the x-axis with one end at x = 0 and the other end at x = L. It has a non-uniform linear charge density given by the function λ(x)--AO + Ax , where λ0 and A are both positive constants. (a) What are the units of NO and A? Explain (b) Suppose...
