Question
The uncertainties in the velocities of two particle, A and B are 0.05 and 0.02 ms-1 respectively. The mass of B is five time to that of the mass of A. What is the ratio of uncertain ties 
in their position ?
in their position ?Options
A.2
B.0.25
C.4
D.1
Solution
Using the relation,
ᐃx.ᐃv =
[Heisenberg uncertainty principle]
or ᐃx =
Thus, ᐃxA =
......(i)
ᐃxB =
.......(ii)
Dividing (i) by (ii), we get
or 2
