A beam of radiation is passed between a pair of charged plates as indicated in the fig above. Beam P is undetected While Q is deflected to the left. P and Q respectively should be
I.γ-rays β-rays
II. x-rays β-rays
III. γ-rays x-rays
IV. x-rays x-rays
studying the charges of the Gamma, Alpha, Beta and X-rays, you find that both the x-rays and theGamma rays possess zero-charge hence they could pass the charged plate undetected while the beta rays are negatively charged hence will deflect towards the positive charge of the plate. Alpha rays, on the other hand, are poisitively charged hence, they deflect towards the negative charge.
