Write an equation for the buildup ux ϕB(R) at the surface of a spherical protect of burliness R if a summit origin is located at the benevolence of the protect and the compute of the rectirectilinear wasting coefcient is μ. Assume that the summit origin results in a compute of ϕo for the particle ux at the benevolence of the protect.
