An infinite line of charge with linear density λ1 = 6.6 μC/m is positioned along the axis of a thick insulating shell of inner radius a = 2.9 cm and outer radius b = 4.7 cm. The insulating shell is uniformly charged with a volume density of ρ = -728 μC/m3. What is Ey(P), the value of the y-component of the electric field at point P, located a distance 8.9 cm along the y-axis from the line of charge?

Question

An infinite line of charge with linear density λ1 = 6.6 μC/m is positioned along the axis of a thick insulating shell of inner radius a = 2.9 cm and outer radius b = 4.7 cm. The insulating shell is uniformly charged with a volume density of ρ	 = -728 μC/m3. What is Ey(P), the value of the y-component of the electric field at point P, located a distance 8.9 cm along the y-axis from the line of charge?

Your question is a little absurd.. 
is the line of charge positioned along x axis ?
