 The power dissipated through the segment is just $$P_1=I_1 \Delta V_1 = 5 \text{ W}$$
-Now, for segment 2. We can use [[184_notes:r_energy#Conservation_of_Charge_in_Circuits|what we know]] about charge in steady state circuits to determine the electric field: $$E_2=\frac{A_1}{A_2}E_1 = \frac{\pi d_1^2}{\pi d_2^2}E_1=9E_1=4.5\text{ V/m}$$
