Question

following the discovery of radioactivity in 1896, researchers working with radiation emitted from materials such as pitchblende observed that the emissions followed three different paths between electrically charged plates. Form the sketch below, it appears that

positive plate radioactive source negative plate (A) β is positively charged, γ and α are negatively charged (B) β is negatively charged. γ and α are positively charged (E) none of the above.

Answer 1

(D) is correct option.

$\beta$is negatively charged because it is attracted towards positive plate.

$\gamma$is neutral because it doesnt undergo any deviation.

$\alpha$ is positively charged because it is attracted towards negative plate.

There is attraction between oppositely charged objects.
