Question

From the Heisenberg uncertainty principle how do you calculate x for each of the following:
(a) an electron with v = 0.340 m/s
(b) a baseball (mass = 145 g) with v = 0.200 m/s?

Solution
Verified by Toppr

(a) $$\Delta x \geq 0.170 mm$$
(b) $$\Delta x \geq 1.82 \times 10^{-33}$$ m

Q3
Assuming an electron is confined to a 1nm wide region, find the uncertainty in momentum using Heisenberg Uncertainty principle $$(\Delta x \times \Delta p \cong h)$$. You can assume the uncertainty in position $$\Delta x$$ as 1nm. Assuming $$p \cong \Delta p$$, find the energy of the electron in electron volts.
