If in Bohr's model, for unielectronic atom, time period of revolution is represented as `T_(n,z)` where n represents shell no. and Z represents atomic number then the value of `T_(1,2) : T_(2,1)` will be :

A

`8:1`

B

`1:8`

C

`1:1`

D

`1:32`

Text Solution

Verified by Experts

The correct Answer is:
4
`Tprop(n^(3))/(Z^(2)),(T_(1,2))/(T_(2,1))=(1)/(4)xx(1)/(8)=(1)/(32)`
