HW5, Problem 4 **Spoiler**

Almost done!
V_21=V_2-V_1=-∫_(P_1)^(P_2)▒〖E∙dl〗 Equation 3.39 page 80 (International Edition)
E=r ̂ ρ_l/(2πε_0 r) Eq 3.33 p 78 (International Edition)
V_21=-∫_(r_1)^(r_2)▒〖ρ_l/(2πε_0 r)∙dr〗
V_21=(-ρ_l)/(2πε_0 ) ∫_(r_1)^(r_2)▒〖1/r∙dr〗
V_21=(-ρ_l)/(2πε_0 ) ln(r_1/r_2 )
V_21=ρ_l/(2πε_0 ) ln(r_2/r_1 )
