The position and velocity of an can be determined precisely

The position and velocity of earth can be determined simultaneously with a fair degree of accuracy.Comment.

Assertion (A) : The position of electron can be determined with the help of an electronic microscope. Reason (R) : The product of uncertainty in momentum and the uncertainty in the position of an electron cannot be less than a finite limit.

The activation energy of a reaction can be determined by

The activation energy of a reaction can be determined by

If position and momentum of an electron are determined at a time then value of DeltaP is obtained 3DeltaX , now the uncertainity in velocity of electron will be :-

The motion of a body is represented by the following displacement-time graph. How can the velocity of the body be determined from the above graph?

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 uncertainty in position and momentum are equal, the v uncertainty in velocity would be
