प्रश्न
The diagram in figure shows a radioactive source S placed in a thick lead walled container. The radiations given out are allowed to pass through a magnetic field. The magnetic field (shown as ×) acts perpendicular to the plane of paper inwards. Arrows shows the paths of the radiation A, B and C.
- Name the radiations labelled A, B and C.
- Explain clearly how you used the diagram to arrive at the answer in part (a).

उत्तर
- The radiations are-
- A → γ radiation
- B → α radiation
- C → β radiation
-
- The radiation labelled as A pass undeviated which means that they are uncharged (or neutral) so they must be γ radiations.
- The radiation labelled as B turn to the left which means that they are positively charged so they must be α radiations.
- The radiation labelled as C turn to the right which means that they are negatively charged so they must be β radiations.

The figure shows a radioactive source S placed in a thick-walled lead container. The radiations given off pass through a magnetic field acting in direction perpendicular to the plane of paper inwards as shown by X. Copy the diagram and show the path of radiations.
