Solution

Diagram showing the paths of $α, β, γ$ -radiations

Explanation about $α, β, γ$ -radiations
1. The $β$ -particles are similar to electrons that are negatively charged particles. Hence these $β$ -rays are deflected towards the positively charged plate.
2. The $α$ - particles are identical to the helium nucleus that is positively charged and hence deflected towards the negatively charged plate.
3. The $γ$ -rays are neutral which means they have no charge and hence they are not deflected towards any of the plates.
