The position and velocity of an can be determined precisely

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. 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

Assertion(A): It is not possible to predict position and the velocity of an electron exactly and simultaneously Reason(R): Electron moving with high speed possesses both the particle nature and the wave nature

It is impossible to determine simaltancously the position of velocity of small mictroscopic particle such as electron , proton or neutron with accoracy .This is called Heisenberg's uncertainty principal, Malthematically, it is represenites as Delta x. Delta p ge (h)/(4pi) Delta x is uncertainty in position Delta p is uncertainty in momentum
