In the Bhor's models for the unielectronic species followingf symbols are used.
`r_(n,z) rarr` Radius of `n^(th)` orbit with atomic number "Z"
`U_(n,z)rarr`Potential energy of electron in `n^(th)` orbit with atomic number "Z"
`K_(n,z)rarr`Kinetic energy of electron in `n^(th)` orbit with atomic number "Z"
`v_(n,z)rarr`Velocity of electron in `n^(th)` orbit with atomic number "Z"
`T_(n,z)rarr`Time period of revlution of electron energy of electron in `n^(th)` orbit with atomic number "Z"
Calulate z in all in cases.
Represent your answer as abcd, where a,b,c and d repersent number from 0 to 9. a,b,c and d
represents the value of "z" in parts (i),(ii),(iii) & (iv) . Suppose your answer is 1,2,3&4 then the same
must be filled in OMR sheet as 12314.00.

Answer

1233

Explanation

Put in the standard equation of radius , velocity potential energy & time peroid and calculate z and its
value comes out to be 1,2,3,3 respectively .
