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]
Explain why alpha and beta particles are deflected in an electric or a magnetic field, but gamma rays are not deflected in such a field.
Is it possible to deflect γ - radiations in a way similar to α and β -particles, using the electric or magnetic field? Give reasons.
State following four properties each of α, β and γ radiations:
- Nature,
- Charge,
- Mass and
- Effect of electric field.
Arrange the α, β, and γ raditions in ascending order of their ionising powers.
State the speed of each of α, β and γ radiations.
What is the composition of α, β and γ radiations?
Compare the ionising powers of α, β and γ radiations.
