Heisenberg Online Assessment Question

Postby FizaBaloch1J » Wed May 02, 2018 12:08 am

I also had a question on how to go about solving this Heisenberg Uncertainty problem.

The problem reads...

The hydrogen atom has a radius of approximately 0.05 nm. Assume that we know the position of an electron to an accuracy of 1 % of the hydrogen radius, calculate the uncertainty in the speed of the electron using the Heisenberg uncertainty principle.

So what I know is that deltax is .05nm which I should then convert into m which would become .05 x 10^-9 m. And we are solving for deltav? so do we use deltap=(m)deltav to solve for it? Is m the mass of an electron which is a constant and then deltap is .01? I am not sure if that's right. Or do we solve for deltap by the equation deltap x deltax > h/4pi and use that delta p to solve for deltav?

This tells us

Yes, we are solving for in and using that to solve for in
