Assuming the nuclei to be spherical in shape, how does the surface area of a nucleus of mass number A_(1) compare with that of a nucleus of mass number A_(2).

Answer»

Solution :Since radius of a nucleus `R propA^(1/3)` , HENCE SURFACE area `SpropA^(2/3)`
`IMPLIES S_(1)/S_(2)=(A_(1)/A_(2))^(2/3)`.
