The uncertainty in position of an electron is 12 Å. Determine the minimum uncertainty in momentum and also the corresponding uncertainly in kinetic energy. (Ans. Ap = 8.79 × 10-26 kg-m/s, AE = 0.0265 eV) An electron's energy is measured with an uncertainty of 1.2 eV. What is the minimum uncertainty in time over which the energy is measured'?($ 91-01 × 6t = /V 'suy)
