Figure 26-24a gives the magnitude E(x) of the electric fields that have been set up by a battery along a resistive rod of length 9.00 mm . The rod consists of three sections of the same material and length but with different radii. The radius of section 3 is 5.00 mm.(adsbygoogle = window.adsbygoogle || []).push({});

E for section 1 is 2.5e3V/m, E for section 2 is 4e3V/m,

E for section 3 is 1.5e3V/m

I understand that p is the same for all of them put I am getting stuck after that
