Two heavy wires spaced 3.5 m apart on a 50 hz ac powerline carry equal and opposite currents, with suspension poles located 500 m apart. (a) what is the peak and rms total magnetic force between these two wires. specify any assumptions in making this estimate. [8] (b) at what frequency would the wires vibrate? [2] (c) if the droop at the midpoint between power poles was 5 m, and the mass of the cable was 0.8 kg/m, by how much would the separation at the midpoint change for 1000 amps of rms current?
