Question

a ball has mass of50g and speed of 30m/s if the speed can be measured within accuracy of2% then the uncertanity in the position is​

Answer 1

Answer:

__________________________❤*⃣

Δv = 2

Δx = ?

According to Heisenberg uncertainty principle

Δx * mΔv >= h/4pie

$\huge{x \times 0.05 \times 30 = \frac{h}{4\pi} }$

$\huge{x \times 1.5 = \frac{h}{4\pi} }$

$\huge{x \: = \frac{h}{6\pi} }$
