Questions
The uncertainties in the velocities of two particles A and B are 0.05 and 0.02 ms-1 respectively. The mass of B is five times to that of mass A. What is the ratio of uncertainties in their positions?
detailed solution
Correct option is A
According to Heisenberg,Δx×m×Δv=h4πwhere, Δx= uncertainty in position m= mass of particleΔv= uncertainty in velocity According to question,ΔxA×m×0.05=h4πΔxB×5m×0.02=h4πDivide Eq. () by Eq. (i), then⇒ ΔxAΔxB=5m×0.02m×0.05=2 or ΔxAΔxB=2Similar Questions
