Determining the mass of an electron

Assignment Help Physics
Reference no: EM131197424

The Bohr radius of the hydrogen atom is 0.529 ?, or 0.0529 nm. Assuming that we know the position of an electron in this orbit to an accuracy of 1% of the radius, calculate the uncertainty in the velocity of the electron. Be sure to include units in all calculations. (Note: Use the equation ΔxΔp=h, where h is equal to Planck's constant, approximately 6.626 x 10-34 J s. The mass of an electron is approximately 9.11 x 10-31 kg.)
