Suppose a beam of 50 ev protons strikes a potential energy, Ask an Expert

Academics

Suppose a beam of 5.0 eV protons strikes a potential energy barrier of height 5.5 eV and thickness 0.59 nm, at a rate equivalent to a current of 1005 A.

(a) How long would you have to wait-on average-for one proton to be transmitted?

(b) How long would you have to wait if the beam consisted of electrons rather than protons?
