A) \[50\text{ }kg\,m{{s}^{-}}^{1}\]
B) \[60\text{ }kg\,m{{s}^{-}}^{1}\]
C) \[80\,\,\times \,\,{{10}^{-26}}\,\,kg\,ms{{\,}^{-1}}\]
D) \[50\,\,\times \,\,{{10}^{-26}}\,\,kg\,ms{{\,}^{-1}}\]
Correct Answer: D
Solution :
The product of uncertainties in the position and the momentum of a subatomic particle\[=\,\,h/4\pi \]. Since \[\Delta x\] is the same for electron and helium, so \[\Delta p\] must be the same for both the particles, i.e., \[50 \times 1{{0}^{-}}^{26}kg\,m{{s}^{-}}^{1}\] (given).You need to login to perform this action.
