An infinitely long solid insulating cylinder of radius a = 5.4 cm is positioned with its symmetry axis along the z-axis as shown. The cylinder is uniformly charged with a charge density p = 34 HC/m². Concentric with the cylinder is a cylindrical conducting shell of inner radius b = 11 cm, and outer radius c = 14 cm. The conducting shell has a linear charge density λ = -0.53μC/m. N/C Submit 1) What is E, (R), the y-component of the electric field at point R, located a distance d = 40 cm from the origin along the y-axis as shown? R(0,d) Submit Ov(a) <0 Ov(a) = 0 Ov(a) > 0 Submit 2 2) What is V(P) - V(R), the potential difference between points P and R? Point P is located at (x,y) = (40 cm, 40 cm). P(dd) Submit 3) What is V(c) - V(a), the potentital difference between the outer surface of the conductor and the outer surface of the insulator? 4) Defining the zero of potential to be along the z-axis (x = y = 0), what is the sign of the potential at the surface of the insulator? + 5) The charge density of the insulating cylinder is now changed to a new value, p' and it is found that the electric field at point P is now zero. What is the value of p'? uC/m³ Submit
