For two concentric spheres with radii r, = a and rz = b , with a<b , the temperature T(r) of
the region between the spheres at a distance r from the center is determined by solving the
following boundary value problem:
37" (r) + 2T' (r) = 0
T(a) = to T(b) =t,
Where t, and t, represent the temperature of the surface in each of the spheres, respectively.
Consider two concentric spheres with radii r = 2cm and rz = 4cm and surface temperatures
of 10°C and 30°C, respectively, Determine the temperature T(r) of the region between the two
spheres at a distance r from the center
3T"(r) + 27'(r) = 0
T(2) = 10
%3D
T(4) = 30
%3D
(a) Determine, using only higher-order linear differential equation solving techniques, the
solution to the boundary value problem.
