A microscope using suitable photons is employed to an electron in an atom within a distance of `0.1 Å`. What is the uncertainty involved in the measurment of its velocity? Mass of electron `= 9.11 xx 10^(-31) kg` and `h = 6.626 xx 10^(-34) J s`

Options

A. `2.69 xx 10^(6)ms^(-1)`
B. `5.79 xx 10^(5)ms^(-1)`
C. `5.79 xx 10^(6)ms^(-1)`
D. `4.62 xx 10^(6)ms^(-1)`

Answer

C

Explanation

`Deltax.m.Deltav = (h)/(4pi)`
