The uncertainty in the position of an electron moving with a velocity of `1 xx 10^4 cm s^-1` (accurate up to `0.011 %`) will be :

Options

A. `1.92 cm`
B. `7.68 m`
C. `0.528 cm`
D. `3.84 cm`

Answer

C

Explanation

Apply the formula `Delta x = (h)/(4pi xx m xx Delta v)`
`= (6.6 xx 10^(-27) xx 100)/(4 xx 3.14 xx 9.1 xx 10^(-28) xx 1 xx 10^(4) xx 0.011)`
`= 0.528 cm`.
