A short conducting rod P of length `3.0 cm` is placed parallel to an near the centre of a long conducting rod Q of length 3.0 m. Conductors P and carry currents of 3.0 A and 4.0 A respectively in the same direction. The two conductors are separated by a distance of `2.0 cm` in air. What is the force experienced by the long conductor Q ?
