Question

The mass of an electron is 9.11× 10–31 kg. What is the uncertainty in the position of an electron moving at 6.00 × 106 m/s with an uncertainty of ?v = 0.01 × 106 m/s?

German physicist Werner Heisenberg related the uncertainty of an object's position (Ax) to the uncertainty in its velocity . where h is Planck's constant and m is the mass of the object. TTmAV The mass of an elers9110kg What is the uncertainty in the position of an electron moving at 6.00 x10 m/s with an uncertainty of Av = 0.01 x 10° mis? The mass of an electron is 9.11x 10-3 kg. Number -64 114.74× 10 In

Explanation / Answer

Delta x > h / (4*pi*m*dv)

Delta x > 6.62*10^-34 / (4*3.14*9.11*10^-31*6*10^6)

Delta x > 9.64*10^-12 m
