Calculate the uncertainty in velocity of an oxygen molecule `(5.3xx10^(-26) kg)`, trapped within a sac of average diameter `5xx10^(-10)` m.

A

3.11 m/sec

B

2.65 m/sec

C

4.31 m/sec

D

1.99 m/sec

Text Solution

Verified by Experts

The correct Answer is:
D
Uncertainity in position `Delta x=` Diameter of sac `=5xx10^(-10) m`
`Delta x Delta v ge (h)/(4 pi m)," "Delta v ge (6.626xx10^(-34))/(4xx3.14xx5.3xx10^(-26)xx5xx10)~~1.99" m/sec"`
