An infinite line of charge with linear density λ1 = 6.0 μC/m is positioned along the axis of a thick insulating shell of inner radius a = 2.6 cm and outer radius b = 4.3 cm. The insulating shell is uniformly charged with a volume density of ρ = -624.0 μC/m^3.

What is Ey(P), the value of the y-component of the electric field at point P, located a distance 6.6 cm along the y-axis from the line of charge?

What is Ex(R), the value of the x-component of the electric field at point R, located a distance 1.3 cm along a line that makes an angle of 30 degrees with the x-axis?

What is Ey(R), the value of the y-component of the electric field at point R, located a distance 1.3 cm along a line that makes an angle of 30 degrees with the x-axis?

For Ey(P), I've already tried $$\frac{ \lambda _{2} }{ 2 \pi \epsilon _{0}r}$$, where r = 0.066 m and lambda2 was found earlier to be $$(vol _{outer-}vol _{inner})*\rho$$

when you say shell.. is it like a sphere?? or a cylinder?.. its a cylinder right? :D
