The acceleration of electron in the first orbit of a hydrogen atom is (where the symbols have their usual meanings)

A

`(4 pi^(2) m)/(h^(3))`

B

`(h^(2))/(4 pi^(2)mr)`

C

`(h)/(4 pi^(2)m^(2)r^(3))`

D

`(m^(2)h^(2))/(4 pi^(2)r^(3))`

Text Solution

Verified by Experts

The correct Answer is:
C

`mvr = (h)/(2 pi)` in first orbit
`v = (h)/(pi mr)`
`:. a = (v^(2))/(r ) = (h^(2))/(4pi^(2)m^(2)r^(3))`
