If you are driving a car of mass $1050 \, kg$ at a speed of $90 \, km/h$ and the uncertainty in the velocity of the car is $1 \, \%$,what will be the uncertainty in its position?

Find the uncertainty in the position of an electron which is moving with a velocity of $2.99 \times 10^4 \ cm \ s^{-1}$,accurate up to $0.0016 \%$. (Given,$m_e = 9.1 \times 10^{-28} \ g, h = 6.626 \times 10^{-27} \ erg \cdot s$)

The uncertainty in momentum of an electron is $1 \times 10^{-5} \ kg \ m/s$. The uncertainty in its position will be $(h = 6.62 \times 10^{-34} \ kg \ m^2/s)$

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 .....

An accelerated electron has a speed of $5 \times 10^{6} \ m \ s^{-1}$ with an uncertainty of $0.02 \ \%$. The uncertainty in finding its location while in motion is $x \times 10^{-9} \ m$. The value of $x$ is $......$ (Nearest integer)

Uncertainty in position of a $0.25 \ g$ particle is $10^{-5} \ m$. What is the uncertainty in its velocity? (Given: $h = 6.6 \times 10^{-34} \ J \ s$)
