A collimated beam containing alpha (α\alphaα), beta-minus (β−\beta^-β−), and gamma (γ\gammaγ) radiations from a radioactive source enters a region of uniform magnetic field directed perpendicularly into the plane of the page, as shown in the diagram below.
Which row in the table correctly identifies the paths taken by the α\alphaα, β−\beta^-β−, and γ \gamma\,γ radiations?
α\alphaα: Path R; β−\quad \beta^-β−: Path P; γ\quad \gammaγ: Path Q
α\alphaα: Path P; β−\quad \beta^-β−: Path R; γ\quad \gammaγ: Path Q
α\alphaα: Path P; β−\quad \beta^-β−: Path Q; γ\quad \gammaγ: Path R
α\alphaα: Path R; β−\quad \beta^-β−: Path Q; γ\quad \gammaγ: Path P
