In an atom, an electron is moving with a speed of `600m//s` with an accuracy of `0.005%` certainity with which the positive of the electron can be located is `[h = 6.6 xx 10^(-34)Js,m = 9.1 xx 10^(-31)kg]`

Options

A. `1.52 xx 10^(-4)m`
B. `5.1 xx 10^(-3)m`
C. `1.92 xx 10^(-3)m`
D. `3.84 xx 10^(-3)m`

Answer

C

Explanation

`Delta x.m. Delta x ge (h)/(4p), Delta x ge (h)/(4pi.m.Deltav)`
`Deltax ge = (6.6256 xx 10^(-34))/(4 xx 3.14 xx 9.1 xx 10^(-31) xx (600 xx 0.005)/(100))`
