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}{\ms}^{-1}. The minimum uncertainty in the measurement of the momentum of the helium atom is

Correct Answer is : 5.0×10−26kgms−1

8.0 \times10^{-26} {\kg} {\ms}^{-1}

5.0 \times10^{-26} {\kgms}^{-1}

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

50‌kg‌ms−1
80‌kg‌ms−1
8.0×10−26‌kg‌ms−1
5.0×10−26kgms−1
