The position of both, an electron and a helium atom is known within 1.0 nm. Further the momentum of the electron is known within 5.0 × 10 − 26 kgms − 1 . The minimum uncertainty in the measurement of the momentum of the helium atom is

Question

Aicharya · Accepted Answer

According to uncertainty principle the product of uncertainty in position and uncertainty in momentum is constant for a particle.

i.e.,

Δ x \times Δ p = \frac{h}{4 π}

As

Δ x = 1.0

nm for both electron and helium atom, so

Δ p

is also same for both the particle.

Thus, uncertainty in momentum of the helium atom is also

5.0 \times 1 0^{- 26} k g m s^{- 1}
