The equation $\Delta x \cdot \Delta p \geqslant \frac{h}{4\pi}$ represents:

What parameters are required to determine the position of an electron? Explain.

According to the Heisenberg uncertainty principle,which of the following expressions is correct?

The uncertainty in the position of an electron is $1 \, \mathring{A}$. Find the uncertainty in its velocity.

The product of uncertainty in the position and uncertainty in the velocity of a particle is $5.79 \times 10^{-5} \ m^2 \ s^{-1}$. If the uncertainty in the position is $1 \ nm$,what is the uncertainty in the measurement of its velocity in $m \ s^{-1}$?

An accelerated electron has a speed of $5 \times 10^{6} \ m \ s^{-1}$ with an uncertainty of $0.02 \ \%$. The uncertainty in finding its location while in motion is $x \times 10^{-9} \ m$. The value of $x$ is $......$ (Nearest integer)
