To solve the problem of finding the uncertainty in the momentum of an electron when the uncertainty in its position is zero, we can follow these steps: ### Step-by-Step Solution: 1. **Understand Heisenberg's Uncertainty Principle**: The principle states that the product of the uncertainties in position (Δx) and momentum (Δp) of a particle cannot be smaller than a certain value. Mathematically, it is expressed as: \[ Δx \cdot Δp \geq \frac{h}{4\pi} ...

It is not possible to determine precisely both the position and momentum (or velocity) of a small moving particle such as electron, proton etc. This is known as Heisenberg uncertainty principle. The mathematical form of this principle is : Delta x.Delta p ge (h)/(4pi) (constant) However this principle is irrelevant in case of bigger particles such as a cup, ball, car etc., that we come across in our daily life. If the uncertainty in position of the electron is zero, the uncertainty in its momentum would be

Calculate the uncertainty in the velocity of an electron, if the uncertainity in position is 100 pm.

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 also true. This is summed up in what we now call the Heisenberg uncertainty principle. The equation si deltax.delta (mv)ge(h)/(4pi) The uncertainty in the position or in the momentum of a marcroscopic object like a baseball is too small to observe. However, the mass of microscopic object such as an electon 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 :

What will be the uncertainty in velocity of an electron when the uncertainty in its position is 1000 Å?
