A radioactive source releases $\alpha$-particles, $\beta$-particles and $\gamma$-rays into a vacuum containing a magnetic field. The magnetic field is directed perpendicular to the plane of the paper, into the page. The routes X, Y and Z taken by the three radiations as they pass through the magnetic field are shown. Which radiation travels along path X, path Y and path Z?
- AX: $\alpha$-particles, Y: $\beta$-particles, Z: $\gamma$-rays
- BX: $\alpha$-particles, Y: $\gamma$-rays, Z: $\beta$-particles
- CX: $\beta$-particles, Y: $\alpha$-particles, Z: $\gamma$-rays
- DX: $\beta$-particles, Y: $\gamma$-rays, Z: $\alpha$-particles
