Chapter 12, Problem 53E

Using the Heisenberg uncertainty principle, calculate $\Delta x$ for each of the following.
a. an electron with $\Delta \upsilon =0.100\text{ m/s}$
b. a baseball $\left(\text{mass=145 g}\right)$ with $\Delta \upsilon =0.100\text{ m/s}$
How does the answer in part a compare with the size ofa hydrogen atom? How does the answer in part b correspondto the size of a baseball?
