Answer 1

Answer:

I have don't idea what is question ok

Answer 2

Concept

Because it predicts the frequency at which the nucleus will absorb energy, the Larmor equation is significant. The proton will change its alignment as a result of absorbing the energy, which has a frequency of $1-100 MHz$ in MRI. The charged nucleus in NMR will then display precessional motion at the Larmor Frequency, a distinctive frequency.

Given

Atom is placed in a magnetic field of $0.4T$.

To Find

We have to find the Larmor frequency.

Solution

According to the problem,

Larmor frequency =γ$B/2\pi$.

$=2.68*10^{8} *0.4/2\pi =\frac{1.072*10^{8}}{6.28} =0.1707*10^{8}$$s^{-1}$.

Hence, Larmor frequency is $0.1707*10^{8} s^{-1}$.
