Question

the uncertainty in position of an electron is doubled the uncertainty in position of helium atom . if the uncertainity in momentum of electron is x than the uncertainity in helium atom will be

Answer 1

Answer:

The answer is here

Explanation:

Position of both an electron and a Helium atom = 1 nm

The momentum of an electron =

Uncertainity principle : It is defined as the position and the momentum both can not be determined simultaneously.

According to the Uncertainity principle,

where,

\Delta x\times \Delta p\geq \frac{h}{4\pi}

= position of an atom

\Delta x = position of an atom

\Delta p = momentum of an atom

h = Planck's constant

When the position of an electron and helium atom is same and the momentum of an electron is known then the momentum of helium atom is equal to the momentum of an electron.

Therefore, the momentum of Helium atom is 5\times 10^{-26}Kg.m/s.
