The uncertainty principle gave the concept of:

Each quantum mechanical wave function does not have a readily interpretable physical meaning,but the square of the wave function gives the . . . . . . of finding the electron at a certain point.

"It is impossible to determine simultaneously the exact position and exact momentum of an electron." This statement is called:

Which one is not the correct relation in the following?

The position of both an electron and a helium atom is known within $1.0 \, nm$ and the momentum of the electron is known within $50 \times 10^{-26} \, kg \, m \, s^{-1}$. The minimum uncertainty in the measurement of the momentum of the helium atom is

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