A steady beam of alpha particles (q = +2e) traveling with constant kinetic energy 20 MeV carries
Question:
A steady beam of alpha particles (q = +2e) traveling with constant kinetic energy 20 MeV carries a current of 0.25μA.
(a) If the beam is directed perpendicular to a flat surface, how many alpha particles strike the surface in 3.0 s?
(b) At any instant, how many alpha particles are there in a given 20 cm length of the beam?
(c) Through what potential difference is it necessary to accelerate each alpha particle from rest to bring it to energy of 20 MeV?
