In an atom , an electron is moving with a speed of 600 m/s with an accuracy of `0.05%` . The certainty with which the position of the electron can be located is (h = `6.6 xx 10^(-34) kgm^(2)s^(-1)` , mass of electron , `e_(m) = 9.1 xx 10^(-31)` kg ):

Options

A. `1.52xx10^(-4)m`
B. `5.10xx10^(-3)m`
C. `1.92xx10^(-3)m`
D. `3.84xx10^(-3)m`

Answer

C

Explanation

`Deltax=h/(4pimDeltav),Deltav=0.005/100xx600`
