Question

A stream of positively charged (alpha particles) moving
towords west is defected towords north by a magnetic
field. The direction of magnetic field is :
(a) towords south (b) towords east
(c) downward
(d) upward
Explain this question
​

Answer 1

Answer:

Upwards

Explanation:

Consider this the positively charged particle (alpha particle) is projected towards west is deflected towards north due to a magnetic magnetic field. Therefore, the direction of magnetic field is upward. Here the direction of positively charged alpha particle is towards west this implies the direction of current is also towards west and the direction of magnetic force is towards north. Therefore, according to Fleming's left hand rule, the direction of magnetic field must be upwards.

Answer 2

Answer:

Upward

Explanation:

A positively charged particle anticipated towards west is diverted towards north by an magnetic field. The direction of magnetic field is upward. Here the heading of positively charged alpha particle is towards west this suggests the bearing of current is likewise towards west and the path of magnetic force is towards north. Thus, as indicated by Fleming's left hand rule, the direction of magnetic field will be upwards.
