Question 1

Assume the Heisenberg uncertainty principle can take the form ΔEΔt≥h/4B. How accurate can the position of an electron be made if its speed is 5 × 106 m/s and if the uncertainty in its energy is 10 eV?

◦
7.7 × 10−18 m

◦
1.3 × 10−23 m

◦
6.2 × 10−15 m

◦
1.6 × 10−10 m

◦
1.2 × 10−9 m


Question 2

Assume we can determine the position of a particle within an uncertainty of 0.5 nm. What will be the resulting uncertainty in the particle's momentum (in kg ⋅ m/s)?

◦
1.9 × 10−25

◦
4.2 × 10−25

◦
1.1 × 10−25

◦
1.3 × 10−24

◦
6.6 × 10−25
