A proton with the mass of 1.7*10^-27kg is located in a single dimensional potential well with the width of 2.7*10^-15 m=2.7 fm (approximate diameter of the nucleus) according to the laws of quantum mechanics as a standing wave in the string,the length of the string is equal to the width of potential well.in the state described by the quantum number 3,the wavelength of the proton is----- fm, its linear momentum is ------ kgm/s and its energy is ------mev. How about quantum number 2 and and 1
