the position of both an electron and helium atom is known with in 1.0 nm . the momentum of the electron is known with in 5.0x10^-26 kg m/s. the min uncertainty in the measurement of the momentum of the helium atom is?

According to uncertainity principle, x p .
When the position of eectron and heium atom is same and the momentum of the eectron is known within a range, therefore, the momentum of heium is equal to momentum of electron, i.e. 5.0 x 10 -26 kg m/s
