**Sun Nov 05, 2017 4:34 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.

Comment on your value obtained.

Would you have to multiply the diameter (1*10^-12 m) by 1% in order to find delta x? I tried doing that and it didn't give me the correct answer.
