An MRI machine needs to detect signals that oscillate at very high frequencies. It does so with an LC circuit containing a 15mH coil. To what value should the capacitance be set to detect a 450 MHz signal?

The capacitance is  

Explanation:

From the question we are told that

   The  induction of the LC circuit is  

    The  frequency is  

The natural frequency is mathematically represented as

Where C is the capacitance So  

=>      

substituting values

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
