In partic- ular, when we are dealing with a point charge, we write this equation as 7²6 = 10²2 [əx² + 8² 8² 8² əz² + + 8x² p(r) G(r. r) = --—-8¹ (r-r), -1/-0 where r' = (x, y, z) is the position of the point charge, 63) (r - r') = 8(x − x')6(y-y')(z-z') is the Dirac delta function in three-dimensional space. Solve for G(r, r') by performing a three-dimensional Fourier transform on the Poisson equation, followed by a three-dimensional inverse Fourier transform. You may use the result fd = sin
