Conductive and dielectric cylindrical materials with a thickness of 1 cm and radii of 5 cm and 10 cm, respectively, coaxially around a cylindrical volumetric load of 1 cm thickness; The cartesian coordinate system has angles of 50 with the y- axis and 35 with the z-axis. a) Calculate the values of E, V depending on the radial length r. b) Calculate the Electric Field (E) and Electric Potential (V) values at the point P (20, 25,75). (No need for full result. It can remain as a formula)
