An infinite line of charge with linear density ?1 = 8.5 ?C/m is positioned along the axis of a thick insulating shell of inner radius a = 2.9 cm and outer radius b = 4.0 cm. The insulating shell is uniformly charged with a volume density of ? = -758.0 ?C/m3
1) What is the linear charge density of the insulating shell?
2) What is Ex(P), the value of the x-component of the electric field at point P, located a distance 6.6 cm along the y-axis from the line of charge? (I know this is Zero due to symmetry)
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?
4) What is Ex(R), the value of the x-component of the electric field at point R, located a distance 1.45 cm along a line that makes an angle of 30 degrees with the x-axis?
