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
- ∝-particles are positively charged and have a smaller deviation to the right than β-particles, which are negatively charged and have a larger deviation to the left. Uncharged γ-radiations do not divert and travel in a straight line.
