Which of the following is the $CORRECT$ statement about $\psi^2$?

The uncertainty in the position of a moving bullet of mass $10 \ g$ is $10^{-5} \ m$. Calculate the uncertainty in its velocity.

What will be the mass of a particle if uncertainty in its position is $10^{-8} \ m$ and uncertainty in velocity is $5.26 \times 10^{-25} \ m \ s^{-1}$? ............... $kg$

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

In a $He$ atom,the uncertainty in the position of an $e^-$ is equal to the uncertainty in its momentum $\Delta p$. If the value of $\Delta p$ for the $e^-$ is $32 \times 10^5$,then the value of $\Delta p$ for the $He$ atom is .....

In an atom,an electron is moving with a speed of $600 \ m/sec$ with an uncertainty of $0.005\%$. The uncertainty with which the position of the electron can be located is:
