Which of the following rules states that it is impossible to determine simultaneously the exact position and exact momentum of an electron?

The uncertainty in position is $10^{-10} \ m$ and in velocity is $5.27 \times 10^{-24} \ m \ s^{-1}$. Calculate the mass of the particle.

If the uncertainty in momentum and uncertainty in the position of a particle are equal,then the uncertainty in its velocity would be given by

If uncertainty in position and momentum are equal,then uncertainty in velocity is

In the polar coordinates of the Schrodinger equation,the angle between the radius vector and the $Z$-axis is known as ..........

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 $m \ s^{-1}$?
