Question

# If uncertainty in the position of an electron is zero, the uncertainty in its momentum would be:

A
zero
B
<h/44
C
>h/4π
D
infinite

Solution

## The correct option is D $$infinite$$ According to Heisenberg's Uncertainty Principle, it is impossible to measure position $$x$$ and momentum $$p$$ simultaneously. Use $$\Delta x \Delta p \geqslant h/4\pi$$as $$\Delta x \rightarrow 0, \Delta p \rightarrow \infty$$Here, neither uncertainty can be zero and if the position is zero the uncertainty in momentum becomes infinite.So, option D is correct.Chemistry
