Question

If an electron revolves around a nucleus in a
circular orbit of radius R with frequency n, then the
magnetic field produced at the centre of the
nucleus will be ?​

Answer 1

Answer:

Explanation:

refer to the picture!!!

Answer 2

Given that,

Radius = R

Frequency = n

We know that,

The frequency is

$n=\dfrac{1}{t}$

The charge is

$q=e$

We need to calculate the current

Using formula of current

$I=\dfrac{q}{t}$

$I=qn$

We need to calculate the magnetic field produced at the center of the nucleus

Using formula of magnetic field

$B = \dfrac{\mu_{0}I}{2r}$

Put the value into the formula

$B=\dfrac{\mu_{0}en}{2R}$

Hence, The magnetic field produced at the center of the nucleus is $\dfrac{\mu_{0}en}{2R}$
