Question

A positively charged particle (α-particle) projected towards west is deflected towards

north by a magnetic field. The direction of magnetic field is?​

Answer 1

Answer:

The direction of the magnetic field is in the upward direction in a plane kept parallel to east-west direction.

Explanation:

The direction of force on a moving charge particle by a uniform magnetic field is expressed as F = q (v × B), where F, v and B are all vector quantities. Now if we move the velocity vector along the magnetic field vector and think about the corkscrew rule, then we can easily get the direction of applied the magnetic field.
