An electron has a velocity of $600 \, m/s$ with an accuracy of $0.005 \%$. Calculate the uncertainty in the position of this electron.

$A$ 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 uncertainty in position and momentum are equal,then uncertainty in velocity is

Explain the Schrödinger wave equation and also explain $\psi$ and $|\psi|^{2}$ for a one-electron system.

The effect of the uncertainty principle is significant only for the motion of microscopic particles and is negligible for macroscopic particles. Justify the statement with the help of a suitable example.

State the Heisenberg uncertainty principle.
