    Relativity - energies of particles in circular motion

    Yes and I would like to know the answer - just to know that my reasoning is right or wrong. $$E_{k}=\frac{1}{2}mv^{2}$$ so, as the radius have to remain the same: $$F_{c}=\frac{mv^{2}}{r}$$ As the mass grows up to 2 or 4 the times of single proton you get energy two or four times the...

    Relativity - energies of particles in circular motion

    Summary: What is energy of proton, deuteron and alpha particle in circular motion of the same radius. Hello, I have a problem. Here is the content of an exercise: In some experiment, proton with energy of 1MeV is in circular motion in isotropic magnetic field. What energies would have...
