A positively-charged particle (alpha-particle) projected towards west is deflected towards north by a magnetic field. The direction of magnetic field is ______.
पर्याय
towards south
towards east
downward
upward
उत्तर
A positively-charged particle (alpha-particle) projected towards west is deflected towards north by a magnetic field. The direction of magnetic field is upward.
Explanation:
Applying Fleming's left-hand rule, we can infer that the direction of the magnetic field is upwards.
