Oh sorry, I was calculating the radius wrong. Thanks!

So I tried taking a gaussian surface for the first charge with a radius of (3.05+6.01)/2 = 4.575cm. Then I tried taking a gaussian surface for the second charge with a radius of 3.05 cm. However this is still not working for me... I'm not exactly sure what I'm still doing wrong (λ1) /...

Homework Statement [PLAIN]http://smartphysics.com/images/content/EM/03/h3_lineF.png A cylinder of radius a = 6.1 cm and height h = 9.7 cm is aligned with its axis along the y-axis. An infinite line of charge is placed at x=3.05cm where λ1 = -2 μC/cm and λ2 = 6 μC/cm at x=-3.05 cm. Point P is...
