1.	The position of both an electron and a helium atom is known within `1.0 nm` and the momentum of the electron is known within `50 xx 10^-26 kg ms^-1`. The minimum uncertainty in the measurement of the momentum of the helium atom is.A. `50 kg ms^-1`B. `60 kg ms^-1`C. `80 xx 10^-26 kg ms^-1`D. `50 xx 10^-26 kg ms^-1`
Answer» Correct Answer - D (d) The product of uncertainties in the position and the momentum of a sub atomic particle `= h//4 pi`. Since `Delta x` is same for electron and helium so `Delta p` must be same foe both the particle, i.e., `50 xx 10^-26 kg ms^-1` (given).
