A particle of charge equal to that of an electron, -e, and mass 208 times the mass of electron (called a mu-meson) moves in a circular orbit around a nucleus of charge +3e. (Take the mass of the nucleus to be infinite.) -e A particle of charge equal to that of an electron and mass 208 times the mass of electron (called a mu-meson) moves in a circular orbit around a nucleus of charge +3e.
