Homework Statement
How accurately can the position of a 2.70keV electron be measured assuming its energy is known to 3.00%?
The answer is (deltaX)>=?
Homework Equations
(deltaX)(deltaP)>=h/2pi
(deltaX)(deltaE)>=h/2pi
The Attempt at a Solution
My attempt at this solution was first trying to calculate deltaX using each of the two equations listed above. I was not able to cancel out the units correctly which leads me to believe that the mass of the electron is somehow included (9.11*10^-31 kg).
