Assertion : Both position and momentum of an electron can not be determined simultaneously with maximum accuracy .
Reason : This is because of microscopic nature of electron .

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

In electron microscope which nature of electron is used?

Simultaneous determination of exact position and momentum of an electron is.

The angular momentum of an electron in an orbit is quantized because:

Assertion (A) : We can find the position and velocity of an electron in an atom simultaneously. Reason ® : The short wavelength light interacts with the electron and disturb the motion of the electron.

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 :-
