Question

calculate the uncertainty in velocity of a cricket ball of mass 150g if it's uncertainty the order of 1A​

Answer 1

Correct Question:-

Calculate the uncertainty in the position of a cricket ball of mass 150g if the uncertainty in velocity is 3.52×10^-24m/s.

Answer:-

• mass of ball=150g=0.150kg
• Uncertainty in velocity=∆v=3.52×10^-24m/s

We know

$\boxed{\sf ∆x.m∆v\gt \dfrac{h}{4\pi}}$

$\\ \sf\longmapsto ∆x=\dfrac{6.626\times 10^{-34}kgm^2s^{-1}}{4\times 3.142\times (0.150kg)\times (3.52\times 10^{-24}ms^{-1}}$

$\\ \sf\longmapsto ∆x=10^{-10}m$

$\\ \sf\longmapsto ∆x=1Å$
