Help Uncertainity principle problem

SUMMARY

The discussion centers on applying the uncertainty principle in quantum mechanics to determine the position uncertainty (delta(x)) of a particle given its velocity uncertainty (delta(Vx)). The user has a mass of 2x10^-4 kg with a velocity measurement accuracy of ±10^-6 m/s. To find delta(x), participants suggest calculating the momentum uncertainty (delta(Px)) using the relationship delta(Px) = mass * delta(Vx), and then applying the uncertainty principle formula: delta(x) * delta(Px) ≥ h/4π.

PREREQUISITES
  • Understanding of the Heisenberg Uncertainty Principle
  • Basic knowledge of quantum mechanics (QM)
  • Familiarity with momentum calculations in physics
  • Ability to manipulate equations involving physical constants
NEXT STEPS
  • Calculate momentum uncertainty using delta(Px) = mass * delta(Vx)
  • Research the Heisenberg Uncertainty Principle in detail
  • Explore examples of uncertainty in quantum mechanics
  • Investigate the implications of mass density in quantum systems
USEFUL FOR

Students and enthusiasts of quantum mechanics, physicists exploring the implications of the uncertainty principle, and anyone interested in the foundational concepts of particle behavior in quantum physics.

in my problem i am told
that the x-component of the velocity of a 2x10^-4 kg mass is measured to an accuracy of +_ 10^-6 m/s.
i need to find the limit of the accuracy with which the particle can be located along the x-axis.

the uncertainity principle
delta(x) * delta(Px)>= h/4pi
i have delta(Vx) and i need delta(x)
help please

this is not homework sub-forum, here we post general questions about QM.

someone will move this thread to the right sub-forum, just so know in the future.

Also you need to show some work before you get help.

but I can give you a hint: calculate the deltaP, you have mass and deltaV, it is straightforward.
 
If black holes are described as having no volume of space, yet they are 'mass" via density.
Mass density= MASS per VOLUME of SPACE.
So, density = mass per volume, & in order to MEASURE the density of something is to measure its MASS, then measure its VOLUME then divide MASS/VOLUME.

Why does there seem to be a contradiction?
