A microscope with suitable photons is employed to locate an electron in an atom within a distance of 0.4A. What is the uncertainty involved in the measurement of its velocity?

A mathematical representation is given below: DeltaX xx Deltap_(x) ge h/(4pi) b) If the position of the electron is measured within an accuracy of +-0.002 nm. Calculate the uncertainty in the momentum of the electron.

Statement 1 : The position of an electron can be determined exactly with the help of an electron microscope. Statement 2 : The product of uncertainty in the measurement of its momentum and the uncertainty in the measurement of the position cannot be less than a finite limit.

What is the uncertainty in the position of electron, if uncertainty in its velocity is 0.006 m/s ?

If the electron is to be located within 5xx 10^(-5) A ͦ , what will be the uncertainty in its velocity? (Mass of the electron = 9.1 xx 10^(-31) kg

What is the uncertainty in position of an electron if the uncertainty in its velocity is 5.7 xx 10^(5) m/s ?

Werner Heisenberg considered the limits of how precisely we can measure the properties of an electron or other microscopic particle. He determined that there is a fundamental limit to how closely we can measure both position and momentum. The more accurately we measure the momentum of a particle, the less accurately we can determine its position. The converse is also true. This is summed up in what we now call the Heisenberg uncertainty principle. The equation is Delta x Delta (mv) ge (h)/(4 pi) The uncertainty in the position or in the momentum of a macroscopic object like a baseball is too small to observe. However, the mass of microscopic object such as an electron is small enough for the uncertainty to be relatively large and significant. If the uncertainty in velocity and position is same, then the uncertainty in momentum will be:

An atom has three shells. If there are 4 electröns in the third shell, then a) What is its atomic number? b) What is the number of protons? c) What is the number of electrons? d) Write the method of arrangement of the electron, in the shell?

The uncertainty in position of an electron is equal to its de-Broglie wavelength. The minimum percentage error in its measurement of velocity under this circumstances will be approximately
