An infinite line of charge with linear density λ1 = 8.3 μC/m is positioned along the axis of a thick insulating shell of inner radius a = 2.3 cm and outer radius b = 4.8 cm. The insulating shell is uniformly charged with a volume density of ρ = -536 μC/m3.
1) What is λ2, the linear charge density of the insulating shell?

Question

An infinite line of charge with linear density λ1 = 8.3 μC/m is positioned along the axis of a thick insulating shell of inner radius a = 2.3 cm and outer radius b = 4.8 cm. The insulating shell is uniformly charged with a volume density of ρ	 = -536 μC/m3.
1) What is λ2, the linear charge density of the insulating shell?

anonymous · Answer

To start with, consider unit length of the shell and calculate its volume. To do this you just need to know how to calculate the volume of a cylinder . . . .
