The uncertainty of velocity of an electron is $5.7 \times 10^5 \ m \ s^{-1}$. Find its uncertainty in position.

The electrons are more likely to be found

Heisenberg's uncertainty principle is not valid for:

The mass of particle $A$ is $5$ times that of particle $B$. The uncertainty in their velocities are $0.05 \ ms^{-1}$ and $0.02 \ ms^{-1}$ respectively. What is the ratio of the uncertainties in their positions,i.e.,$\Delta x_A : \Delta x_B$?

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

The uncertainty principle was enunciated by
