Atomic StructureHard

Question

In an atom, an electron is moving with a speed of 600m/s with an accuracy of 0.005%. Certainity with which the position of the electron can be located is (h = 6.6 × 10-34 kg m2s-1, mass of electron, em = 9.1 × 10-34 kg)

Options

A.1.52 × 10-4 M
B.5.10 × 10-3 M
C.9.92 × 10-3 M
D.3.84 × 10-3 M

Solution

ᐃx.m ᐃv =
ᐃx =
ᐃv = 600 × = 0.03
⇒     ᐃx = =1.92 × 10-3 m
