In the Bohr's model , for unielectronic species following symbols are used
`r_(n,z)to` Radius of `n^"th"` orbit with atomic number "z"
`U_(n,z)to` Potential energy of electron in `n^"th"` orbit with atomic number "z"
`K_(n,z)to` Kinetic energy of electron in `n^"th"` orbit with atomic number "z"
`V_(n,z)to` Velocity of electon in `n^"th"` orbit with atomic number "z"
`T_(n,z)to` Time period of revolution of electon in `n^"th"` orbit with atomic number "z"
Calculate z in all in cases.
(i)`U_(1,2):K_(1,z)=-8:9`
(ii)`r_(1,z):r_(2,1) =1:12`
(iii)`v_(1,z):v_(3,1)=15:1`
(iv)`T_(1,2):T_(2,z)=9:32`
Report your answer as (2r-p-q-s) where p,q,r and s represents the value of "z" in parts (i),(ii),(iii),(iv).
