Uncertainty in Electron's Momentum in a 52 x 10-15 m Sphere

Click For Summary
SUMMARY

The discussion focuses on calculating the minimum uncertainty in an electron's momentum when confined in a sphere with a diameter of 52 x 10-15 m. The Heisenberg Uncertainty Principle is applied, where the uncertainty in momentum (p) is determined using the formula p = h / d, with h being Planck's constant (6.626 x 10-34 J·s). The calculation confirms that the approach is correct, establishing a clear method for solving similar problems in quantum mechanics.

PREREQUISITES
  • Understanding of the Heisenberg Uncertainty Principle
  • Familiarity with Planck's constant (h)
  • Basic knowledge of quantum mechanics
  • Ability to perform calculations involving scientific notation
NEXT STEPS

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?

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?

The Attempt at a Solution


p = h / d. I plugged in 6.626E-34 for h and the diameter given. Is this correct?
