Solving a problem in physics section 21 paragraph 70 qu

Product description

• The proton energy E = 5 eV is moving in the positive direction of the x axis, meeting on the way a potential barrier height U = 10 eV and width d = 0,1 nm. Determine the probability of a proton of the barrier. How many times it is necessary to narrow the threshold to the probability of passing its proton it was the same as for the electron in the above conditions.
