Orbital acceleration of electron is

Options

A. `(n^(2)h^(2))/(4pi ^(2)m^(2)r^(2))`
B. `(n^(2)h^(2))/(2n^(2)r^(3))`
C. `(4n^(2)h^(2))/(pi^(2)m^(2)r^(3))`
D. `(4n^(2)h^(2))/(4pi^(2)m^(2)r^(3))`

Answer

A

Explanation

`mvr=(nh)/(2pi)`
`v=(nh)/(2pimr)`
`(v^(2))/(r)=(n^(2)h^(2))/(4pi^(2)m^(2)r^(2))`
