**Mon Oct 26, 2020 4:01 pm**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.

How do I find the uncertainty in the position first? I know once I find it I can just calculate the uncertainty in velocity, but I am struggling on how to find deltax.
