En la figura se muestra un lanzamiento de un proyectil. Si se realiza otro lanzamiento con un ángulo de elevación de -20° y la misma rapidez del lanzamiento horizontal, ¿cómo se comparan los tiempos de vuelo de los dos lanzamientos?

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?
