#### Question

Linear momentum of an electron in Bohr orbit of H-atom (principal quantum number n) is proportional to..................................

- 1/n
^{2} - 1/n
- n
- n
^{2}

#### Solution

(b) 1/n

Linear momentum, p = mv

Velocity of electron in Bohr's orbit is given as

`"v"=e^2/(2epsilon_0"nh")`

`therefore"mv"=e^2/(2epsilon_0"nh")`

`rArr"p"=(me^2)/(2epsilon_0"nh")`

`rArr"p"prop1/"n"`

Is there an error in this question or solution?
