Answer to Question #59059 in Electricity and Magnetism for Emmanuel

Question

Calculate the electric field everywhere outside of a very long rod, radius R and charged to a uniform linear charge density
λ
λ
.

E⃗ =λπrϵ0r^
E→=λπrϵ0r^

E⃗ =λπϵ0ln1rr^
E→=λπϵ0ln1rr^

E⃗ =λ2πrϵ0r^
E→=λ2πrϵ0r^

E⃗ =λ2πϵ0ln1rr^
E→=λ2πϵ0ln1rr^
