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 \times 10^{-26} {kg} {m} {s}^{-1} . The minimum uncertainty in the measurement of the momentum of the helium atom is (1998)

Correct Answer is : 5.0×10−26kgms−1

8.0 \times 10^{-26} {kg} {m} {s}^{-1}

5.0 \times 10^{-26} {kg} {m} {s}^{-1}
