The uncertainty principle gave the concept of:

The uncertainty principle and the concept of wave nature of matter were proposed by ...... and ...... respectively.

Uncertainty in position and momentum are equal. Uncertainty in velocity is :-

Choose the correct statement.

$A$ ball weighing $10 \, g$ is moving with a velocity of $90 \, ms^{-1}$. If the uncertainty in its velocity is $5 \, \%$,then the uncertainty in its position is ....... $\times 10^{-33} \, m$. (Rounded off to the nearest integer) [Given : $h = 6.63 \times 10^{-34} \, Js$]

If the uncertainty in position and momentum of a particle are equal,then what will be the uncertainty in the momentum of the particle?
