1. Homework Statement
an electron is trapped in a sphere whose diameter is 52 x 10-15 m. What is the minimum uncertainty in the electron's momentum?

2. Homework Equations
I know that the uncertainty in the electron's position is equal to the diameter... but how do I set up the equation?


3. The Attempt at a Solution
p = h / d. I plugged in 6.626E-34 for h and the diameter given. Is this correct?

Yes, you're just using the Heisenberg Uncertainty Principle.
