प्रश्न
Radiations given out from a source when subjected to an electric field in a direction perpendicular to their path are shown below in the diagram. The arrows show the path of the radiation A, B and C. Answer the following questions in terms of A, B and C.
1) Name the radiation B which is unaffected by the electrostatic field.
2) Why does the radiation C deflect more than A?
3) Which among the three causes the least biological damage externally.
4) Name the radiation which is used in carbon dating.
उत्तर
1) Gamma radiations
2) Because of the mass of B particle is less than that of α, hence radiation deflects more than A.
3) `gamma` rays
4) beta radiation `""_6^14C -> ""_7^14N + ""_(-1)^0beta^(-)`
