QUESTION$-4.$ Steady$-$state heat transfer in a $10cm$ long flat rod is given by the equation below.

$\frac{d^{2}T}{d{x}^2}+h(T_a-T)=0$

$h=0\mathrm{.}01cm2($heat transfer coefficient$)$

$Ta=20C($ambient temperature$)$

$T(0)=40C$

$T(10)=200C$

Accordingly, find the temperature distribution in the rod using the finite difference method. Give the methcad computer program with its results.
