Calculate the uncertainty in velocity if the uncertainty in the position of a moving bullet of mass 10 gm is $1 0^{- 5} m$ .

Options:

Answer:

Solution:

Uncertainty of moving bullet velocity $Δ υ = \frac{h}{4 π \times m \times Δ υ} = \frac{6.625 \times 1 0^{- 34}}{4 \times 3.14 \times .01 \times 1 0^{- 5}}$

$= 5.2 \times 1 0^{- 28} m / s e c$ .
