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).
