Solution


Q.

The electron emitted in beta radiation originates from            [2001]
1 inner orbits of atoms  
2 free electrons existing in nuclei  
3 decay of a neutron in a nucleus  
4 photon escaping from the nucleus  

Ans.

(3)

In a nucleus a neutron converts into a proton as follows

n→p++e-1

Therefore, decay of neutron is responsible for β-radiation origin.
