How many alpha particles strike the surface

Reference no: EM13654418

A steady beam of alpha particles (q = + 2e)traveling with constant kinetic energy 18 MeV carries a current of 0.30 µA.

(a) If the beam is directed perpendicular to aplane surface, how many alpha particles strike the surface in 3.0s?

(b) At any instant, how many alpha particles are there in a given20 cm length of the beam?

(c) Through what potential difference was it necessary toaccelerate each alpha particle from rest to bring it to an energyof 18 MeV?
