Anyone can explain me this example?(adsbygoogle = window.adsbygoogle || []).push({});

I substitute value for

e = 1.602*10^{-19};

m_{0}= 9.1*10^{-31};

pi = 3.14;

and calculated value for μ_{av}in matlab.

I received 1.7104*10^{-19}. But in exam this value is 0.68*10^{-25}.

What is i wrong?

please help me.

Thank you.
