Two thin concentric shells made from copper with radius`r_1 and r_2 (r_2 gt r_1)` have a material of thermal conductivity K filled between them. The inner and outer spheres are maintained at temperatures `T_H and T_C` respectively by keeping a heater of power P at the centre of the two spheres. Find the value of P.
