The linear speed of the electron in the nth Bohor orbit of the hydrogen atom is proportional to………

Answer»

n
`n^(3)`
`(1)/(n)`
`(1)/(n^(2))`

SOLUTION :`mvr=(nh)/(2pi)`
`impliesv=(nh)/(2pi)xx(1)/(MR)`
For H atom `R=(n^(2)h^(2)epsi_(0))/(pie^(2)m)`
`impliesv=(nh)/(2pi)xx(pie^(2)m)/(n^(2)h^(2)epsi_(0)m)=((e^(2))/(2hepsi_(0)))xx(1)/(n)`
`impliesv=(nh)/(2pi)xx(pie^(2)m)/(n^(2)h^(2)epsi_(0)m)=((e^(2))/(2hepsi_(0)))xx(1)/(n)`
