If the kinetic energy of an electron is known to lie between 1.59 x10-19J and 1.61x10-19J, what is the smallest distance within which it can be known to lie?Compare those results to a similar calculation for the He atom instead of an electron. I don't need the answer to the first one, I am just confused on how to approach the second question. Don't I need velocity to do this calculation?

To answer your question, yes, you will need the velocity in order to solve the second part and as…
