प्रश्न
In following Figure shows a mixed source R of alpha and beta particles in a thick lead walled container. The particles pass through a magnetic field in a direction perpendicular to the plane of paper inwards as shown by ×.
- Show in the diagram how the particles get affected.
- Name the law used in part (a).
[Hint: Alpha particles will deflect to the left while beta particles to the right]

उत्तर
(a)
(b)
Alpha particles (α): positively charged → will be deflected to the left.
Beta particles (β): negatively charged → will be deflected to the right.
The direction of deflection in a magnetic field is given by Fleming’s left hand rule.
-
Thumb → direction of force (deflection)
-
Forefinger → direction of magnetic field (into the page)
-
Middle finger → direction of current or moving charge (upward).
