Question

DO PART B ONLY

An electron and a 0.0340 kg bullet each have a velocity of magnitude 450 m/s, accurate to within 0.0100%. Within what lower limit could we determine the position of each object along the direction of the velocity? (Give the lower limit for the electron in mm and that for the bullet in m.)

(b)

What If? Within what lower limit could we determine the position of each object along the direction of the velocity if the electron and the bullet were both relativistic, traveling at 0.400c measured with the same accuracy? (Give the lower limit for the electron in nm and that for the bullet in m.)

Answer 1

Electron's kinetic energy is

in eV

Then

The compton shift is

(if answer was asked in pm then it is 2.31144 pm)
