An argon positive ion fired towards east gets deflected towards south by a magnetic field. The direction of magnetic field is:
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. upward.
Explanation:
-
When a positively charged particle moves through a magnetic field, it experiences a force that deflects it in a particular direction.
-
In this case, the ion is moving towards the east and gets deflected towards the south.
-
Using the right-hand rule (thumb points in the direction of motion, palm faces in the direction of the force, fingers show the magnetic field),
-
If the motion is east and the deflection is south, then the magnetic field must be upward to cause such a deflection.
-
Therefore, the direction of the magnetic field is upward.
