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]`

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

Text Solution

Verified by Experts

The correct Answer is:
C
`Delta x .m.Delta v ge (h)/(4pi)" "Deltax ge (h)/(4pi.m.Deltav)`
`Delta x ge (6.6256 xx 10^(-34))/(4 xx 3.14 xx 9.1 xx 10^(-31) xx (600 xx 0.005)/(100))`
