Question: (a) Calculate the electric potential difference needed to accelerate a proton so that it has a wavelength of 1.0x10 -12 m. (b) Repeat the calculation

(a) Calculate the electric potential difference needed to accelerate a proton so that it has a wavelength of 1.0x10-12 m. 

(b) Repeat the calculation for an electron. Here you must use the relativistic expressions for energy and momentum. 

(c) Compare the energies of these two particles (ratio of proton energy to electron energy) when they have this same wavelength.
