It is impossible to determine simultaneously the position of velocity of small microscopic particle such as electron , proton or neutron with accuracy .This is called Heisenberg's uncertainty principle. Mathematically, it is represented as Delta x. Delta p ge (h)/(4pi) , Delta x is uncertainty in position Delta p is uncertainty in momentum.

According to Heisenberg's uncertainty principle, on increasing the wavelength of light used to locate a microscopic particle, uncertainly in measurement of position of particle :

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. In case of small microscopic particles, Heisenberg's uncertainty principle rules out simultaneous exact determination of their

It is not possible to determine preciselt both the position and momentum (or velocity) of a small moving particle such as electron, proton etc. This is known as Heisenber uncertainty principle. The mathemactical form of this principle is : Delta x.Delta p ge (h)/(4pi) (constant) However this principle is irrevalent in case of bigger particles such as a cup, ball, car etc., that we come across in our daily life. Given that the mass of electron is 9.1 xx 10^(-31) kg and velocity of electron is 2.2 xx 10^(6) ms^(-1) , if uncertainty in its velocity is 0.1% , the uncertainty in position would be

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. What would be the minimum uncetaintty in de-Broglie wavelength of a moving electron accelerated by potential difference of 6 volt and whose uncetainty in position is (7)/(22) nm?

Statement-1 : It is not necessary for a particle to move in a circular path to define angular momentum. It can be defined about any point in space. Statement-2 : Particle moving in a straight line has non-zero angular momentum about a point which is not lying on the path of the particle.
