The uncertainty in the position of a moving bullet of mass 10 gm is 10−5 m. Calculate the uncertainty in its velocity
5.2 X 10-28 m/sec
3.0 X 10-28 m/sec
5.2 X 10-22 m/sec
3 X 10-22 m/sec
Uncertainty of moving bullet velocity
△v=h4π×m×△v=6.625×10−344×3.14×.01×10−5
=5.2×10−28m/sec.
The uncertainty in momentum of an electron is 1×10−5kg−m/s. The uncertainty in its position will be (h=6.62×10−34kg−m2/s)
