A microscope using suitable photons is employed to locate an electron in an atom within a distance of 0.1 Ã…. What is the uncertainty involved in the measurement of its velocity ?

Explanation

`Deltax Deltap = h/(4pi)or Deltax mDeltav= h/(4pi)`
`= 4/(4 piDeltaxm)`
`Deltav=(6.626xx10^(-33)Js)/(4xx3.14xx0.1xx10^(-10)mxx9.11xx10^(-31)kg)`
`0.579xx10^(7)ms^(-1)(1J = 1 kg m^(2)s^(-2))`
`5.79xx10^(6)ms^(-1)`
