(a)
Interpretation:
The reason for the alpha and beta radiation to be separated by an electric field needs to be explained.
Concept introduction:
The opposite charges attract each other. The charge on the beta particles is negative and it will attract towards the plates which are positively charged. Similarly, alpha particles are positively charged, they will attract towards the negativity charged plates.
(b)
Interpretation:
The reason for radioactive C-11 to be used as a tracer to understand the brain disorders needs to be explained.
Concept introduction:
A radiotracer is a chemical compound where one or more atoms are replaced by radioisotopes. The radiotracer helps in tracing the mechanism of the
(c)
Interpretation:
The reason for a self sustaining chain reaction to takes place in nuclear fission needs to be explained.
Concept introduction:
Nuclear fission reaction is a reaction in which nucleus of an atom splits to form smaller nuclei. The products of a nuclear fission reaction are neutrons, protons and large amount of energy.
