An infinitely long solid conducting cylindrical shell of radius a = 4.2 cm and negligible thickness is y positioned with its symmetry axis along the z-axis as shown. The shell is charged, having a linear charge density inner = -0.54 uC/m. Concentric with the shell is another cylindrical conducting shell of inner radius b = 17.8 cm, and outer radius c = 20.8 cm. This conducting shell has a linear charge Nouter density ) outer = 0.54uC/m. Winner P(d,0) 6 C 1) What is Ex(P), the x-component of the electric field at point P, located a distance d = 9.6 cm from the origin along the x-axis as shown? N/C Submit + 2) What is V(c) - V(a), the potential difference between the the two cylindrical shells? V Submit
