It is not possible to determine simultaneously the exact position and the exact momentum of a fast moving micro particle. Explain.

Assertion (A) It is impossible to determine the exact position and exact momentum of an electron simultaneously. Reason (R) The path of an electron in an atom is clearly defiened.

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. 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. If the uncertainty in position of the electron is zero, the uncertainty in its momentum would be

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
