1.	A stream of protons is moving parallel to a stream of electrons. Will the two stream tend to come closer or move apart?
Answer» The behaviour of the two streams of protons and electrons coming closer or moving apart depends on their speed. If they have large speeds, they will move apart because the magnetic interaction is more repulsive than electrostatic attraction. If they have small speeds, they will come closer to each other as electrostatic attraction between them is stronger than magnetic repulsion between them.
