mportant!!

A 120 kv, 50 Hz voltage was applied to a two layer stranded cable and the second layer was grounded. The diameter of the conductive part of the cable is 2cm, the radius of the first layer on the heart is 2cm, and the radius of the second layer is 4.2cm. The relative dielectric constants of both layers are given as Er = 3.8. since the cable length is 6440 meters a) system's equivalent capacity? b) When the cable is below 120 kV, calculate the potential of the first layer and the current flowing to the ground over the capacities? c) Calculate at what point the maximum electric field intensity occurs with the reactive power produced by the capacities?
