Question 8 (based on material in Unit 19) (a) Heisenberg's uncertainty principle can be expressed as Ar Ap. (Equation 1) Planck's constant is given in units of Js in the S217 Equations Booklet. Use this to show that the units on the left-hand and right-hand sides of Equation 1 are equivalent. (b) An electron moving along the r-axis has an uncertainty in position of 2 x 10-9 m. Calculate the minimum uncertainty associated with a measurement of the z-component of its velocity. [2] [2]
