I actually consider the e. I think I just get the logic error. And from now on, I did not find my logic error.

In this question the mass is 207me.

My instructor does not tells us about virial theorem. Thank you!

So 1/2*m*v^2=13.6*Z^2/2 and v=(13.6*Z^2/m)^(1/2) = 1.6*10^15 m/s that is even more than speed of light.

But in this question v and r are both unknown value. Thanks!

The muon is a subatomic particle with the same charge as an electron but with a mass that is 207 times greater: mμ=207me. Physicists think of muons as "heavy electrons." However, the muon is not a stable particle; it decays with a half-life of 1.5 μs into an electron plus two neutrinos. Muons...

Thank you! The slope on the graph is incorrect. I will report this to mastering physics.

Yes. I choose "T" to be the unit.

Magnetic fields are sometimes measured by balancing magnetic forces against known mechanical forces. Your task is to measure the strength of a horizontal magnetic field using a 12-cm-long rigid metal rod that hangs from two nonmagnetic springs, one at each end, with spring constants 1.3 N/m ...
