Two identical long straight conducting wires with a mass per unit length of 25.0 g/m are resting parallel to each other on a table. The wires are separated by 2.5 mm and are carrying currents in opposite directions.
(a) If the coefficient of static friction between the wires and the table is 0.035, what minimum current is necessary to make the wires start to move?
(b) Do the wires move closer together or farther apart?
