If the position of the electron were measured with an accuracy of +0.002 nm, the uncertainty in the momentum of the electron would be: 

1. 5.637 × 10–23 kg m s–1

2. 4.637 × 10–23 kg m s–1

3. 2.637 × 10–23 kg m s–1

4. 3.637 × 10–23 kg m s–1

Uncertainty in position of a e- and He is similar. If uncertainty in momentum of e- is 32×105, then uncertainty in momentum of He will be:

1. 32 × 105 2. 16×105
3. 8 × 105 4. None of the above
