In an atom, an electron moves in an orbit of radius `r` with a speed `v`, the equivalent current is.

A

`(e v)/(2 pi r)`

B

`(ev)/(2 r)`

C

`(e v)/(2 pi)`

D

`( e)/(2 pi r)`

Text Solution

Verified by Experts

The correct Answer is:
A

`i = (q)/(T) = (e)/(2 pi r//v) = (ev)/(2 pi r), clockwise`.
