Question

Match the following types of rays with the charged plates they were deviated towards during Rutherford's gold foil experiment.

• A. No deviation
• B. Positively charged
• C. Negatively charged

Answer 1

Rutherford and Willard studied the radiation emitted by radioactive substances. It was found that the radiations are of three types.

$\bullet$ ($\alpha$)-rays deviate slightly towards negatively charged plate as these rays are positively charged.

$\bullet$ ($\beta$)-rays deviate towards the positively charged plate as these rays are negatively charged.

$\bullet$ ($\gamma$)-rays do not deviate in the electric field as they are electrically neutral in nature.
