A n-meson is a particle that decays into a muon and a massless particle. The n-meson has a rest mass energy of 139.6 MeV and the muon has a rest mass energy 105.7 MeV. Suppose the n-meson is at rest and all of the missing mass goes into the muon's kinetic energy. How fast will the muon move?

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
