Question

A radioactive source emits three types of radiations. The radiations which are deflected by the electric field are:

• A. $\alpha and\gamma$
• B. $\beta and\gamma$
  
• C. $\alpha and\beta$
  
• D. $\alpha ,\beta ,and\gamma$
  

Answer 1

The correct option is C $\alpha and\beta$

Only charge particle are deflected in electric, so alpha and beta particle will get deflected, as there is no charge in gamma ray it will go un-deflected.
