Orbit acceleration of electron is

Options

A. `(n^(2)h^(2))/(4pi^(2)m^(2)r^(3))`
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) rArr v = (nh)/(2pi mr) rArr (v^(2))/(r ) = (n^(2)h^(2))/(4pi^(2)m^(2)r^(3))`
