Suppose that, for a high-energy experiment to probe the structure of protons, you need electrons with de Broglie wavelength of 1.00×10−16m. What total energy E (including rest energy) would these electrons have?

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
