Two aluminum rods of length 75 cm and mass 50 g are suspended by non conducting cables of length 10 cm as shown in Figure P20.96. The rods are part of a circuit (not shown) that supplies a current I through each rod as shown. If the angle between the two end cables is 4.0°, what is the magnitude of the current I? Assume the rods are very long.
