Heisenberg Uncertainty Principle

Q. Consider two particles: a proton and a shot-gun pellet. The proton (1.7 x 10^-27 kg) is moving at speeds roughly half the speed of light while the shot-gun pellet (2 x 10^-3 kg) is moving at about 250 m/s. Both have 1% uncertainty in their velocities. Which has the greater uncertainty in position? a) The proton b) The shotgun pellet
