Question 7

Medium

A radioactive source that emits alpha ( $α\alpha$ ), beta-minus ( $β−\beta^-$ ), and gamma ( $γ\gamma$ ) radiation is placed in a uniform magnetic field directed perpendicularly out of the page, as shown below. Three distinct paths of radiation, $P$ , $Q$ , and $R$ , are observed.

Deflection of radiation in a magnetic field

Which of the following correctly identifies the radiation types corresponding to paths $P$ , $Q$ , and $R$ ?

$P$ is $α\alpha$ , $Q$ is $γ\gamma$ , $R$ is $β−\beta^-$

$P$ is $β−\beta^-$ , $Q$ is $γ\gamma$ , $R$ is $α\alpha$

$P$ is $β−\beta^-$ , $Q$ is $α\alpha$ , $R$ is $γ\gamma$

$P$ is $γ\gamma$ , $Q$ is $β−\beta^-$ , $R$ is $α\alpha$
