(A) : In the Bohr model of the hydrogen atom, V and E respresent the speed of the electron and the total energy of the electron respectively. Then V/E is proportional to the quantum number n of the electron (R) V alpha n^(-1) and E alpha n^(-2)

Both 'A' and 'R' are true and 'R' is the correct explanation of 'A'.

Both 'A' and 'R' are true and 'R' is not the correct explanation of 'A'

'A' is true and 'R' is false

'A' is false and 'R' is true

`-1`

`-2`

`+2`

`l=2`

`m=2`

`n=3`

`n=4`
