Calculate the velocity of an electron in...

Calculate the velocity of an electron in Bhor's first orbit of hydrogen atom. (Given `r=0.53 xx 10^(-10)m`)

Text Solution

Verified by Experts

According to Bohr's theory,
`mvr=(nh)/(2 pi) " "or" " v=(nh)/(2 pi mr) , r=0.53 xx 10^(-10)m`
`n=1, h=6.62 xx 10^(-34) kg m^(2) s^(-1), m=9.1 xx 10^(-31) kg , pi =(22)/(7)`
`:. " " v=(1xx(6.62xx10^(-34)kgm^(2)s^(-1)))/(2xx(22)/(7)xx(9.1 xx 10^(-31)kg) xx (0.53 xx 10^(-10 )m))=2.18 xx 10^(6)ms^(-1)`
