An infinite uniform non-multiplying medium has the following properties: diffusion length 8cm, diffusion coefficient 1.4 cm. there is an infinite plane source on the y-z of plane strength 13 106cm-2.s-1 and two point sources on the x. y plane as follows source: 82 = 107 s-1 at (x, y) = (1,0)cm s,-107s-1 at (x, y) = (2,0)cm a. calculate the total flux at the point (xn =(1.5,0.5) cm on the x-y plane. flux- b. what is the magnitude and the direction of the total current at the same point current magnitude- current directions:
