An electron moving in a circular orbit...

An electron moving in a circular orbit of radius `r` makes `n` rotation per secound. The magnetic field produced at the centre has magnitude

A

`(mu_(0)n^(2)e)/(2r)`

B

`(mu_(0)ne)/(2pir)`

C

`(mu_(0)ne)/(2r)`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
C
`B=(mu_(0)Ni)/(2r)` but N=1 I =ne `therefore B=(mu_(0)ne)/(2r)`
