Question

in a hydrogen atom an electron is revolving with an angular frequency

Answer 1

Consider an electron of charge (-e) performing uniform circular motion around stationary nucleus of charge (+e)

Therefore,

T= circumference /velocity

T= (2*3.14*r)/V...........................(1)

Now circulating current is give by,

I=e/T.............................(2)

Using (1) in (2),

I=e/(2*3.14*r/V)

I=ev/2*3.14*r

Moment =I*A

Moment =evr/2

Thus equation for moment is

M =evr/2

Answer 2

Answer:

m=evr/2
