A rod of semiconducting material of Length L=2 m and cross-sectional area A=4 mm2 lies along the x-axis between x=0 and x=L. The material obeys ohm’s Law, and its resistivity varies along the rod according to ρ = ρ0*( 1 - x2/L2) where ρ0=3 x 10-4 Ω.m. The end of the rod at x=0 is at potential V0=25 V greater than the end at x=L. What is the electric potential, in units of volt, in the rod at x=L/2?
