Question

# If uncertainity in position and momentum are equal, then uncertainity in velocity is:

A
hπ
B
12hπ
C
12mhπ
D
2m12hπ

Solution

## The correct option is B $$\displaystyle\frac{1}{2m}\sqrt{\displaystyle\frac{h}{\pi }}$$Use,$$\Delta x\Delta p=\displaystyle\frac{h}{4\pi}$$Since, $$\Delta x=\Delta p$$, therefore $$\Delta p=\displaystyle\frac{h}{2\sqrt{\pi}} = \Delta x, \Delta p = m\Delta v$$, Therefore, $$\Delta v=\displaystyle\frac{1}{2m}\sqrt{\displaystyle\frac{h}{\pi }}$$Chemistry
