Question

If uncertainty in position and momentum are equal then uncertainty in velocity is.
A. `sqrt((h)/(pi))`
B. `sqrt((h)/(2 pi))`
C. `(1)/(2m) sqrt((h)/(pi))`
D. None of these

Answer 1

Correct Answer - C
( c) `Delta x Delta p ge (h)/(4 pi)`
`Delta p ge sqrt((h)/(4 pi)) ` when `Delta x = Delta p`
`m Delta v ge sqrt((h)/(4 pi)) , Delta v^3 (1)/( 2m) sqrt((h)/(pi))`.
