Chapter 3, Problem 3.146QP

(a) An electron in the ground state of the hydrogen atom moves at an average speed of 5 × 10⁶ m/s. If the speed is known to an uncertainty of 20 percent, what is the minimum uncertainty in its position? Given that the radius of the hydrogen atom in the ground state is 5.29 × 10⁻¹¹ m, comment on your result. The mass of an electron is 9.1094 × 10⁻³¹ kg. (b) A 0.15-kg baseball thrown at 99 mph has a momentum of 6.7 kg · m/s. If the uncertainty in measuring the momentum is 1.0 × 10⁻⁷ of the momentum, calculate the uncertainty in the baseball’s position.
