An infinite line of charge with linear density A1 = -7C/m is positioned along the axis of a thick conducting shell of inner radius a = 3.4 cm and outer radius b = 5.1 cm and infinite length. The conducting shell is uniformly charged with a linear charge density A2 = 4.6 C/m. 1) What is Ex(P), the electric field at point P, located at (x,y) = (-11.7 cm, 0 cm) ? N/C Submit 5) What is Ab, the linear charge density on the outer surface of the conducting shell ? C/m Submit 6) What is Aa, the linear charge density on the inner surface of the conducting shell ? C/m Submit 7) The charged conducting shell is now replaced by an uncharged conducting shell of the same dimensions. What is Ab, the linear charge density on the outer surface of the uncharged conducting shell ? C/m Submit 8) The conducting shell is now given a new charge (X2,new C/cm) such that the electric field at point P becomes equal to . What must be the sign of Ab, the linear charge density on the outer surface of the charged conducting shell?
