The position of both, an electron and a helium atom is
known within 1.0 mm. Further the momentum of the
electron is known within 5.0 x 10-26 kg m s-1. The
minimum uncertainty in the measurement of the
momentum of the helium atom is

By Heisenberg's Uncertainity principle,
Δx×Δp≥
4π
h
Position of both an electron & a helium atom =1 nm
Momentum of an electron =5×10
−25
kg.m/s
When the postion of both the electron and helium atom is same then the momentum of helium atom is equal to momentum of an electron.
Momentum of Helium atom =5×10
−26
Kg.m/s
