Vedclass · Answer

(D) . The statement "It is impossible to determine simultaneously the exact position and exact momentum of an electron" is the definition of the $Heisenberg \ uncertainty \ principle$.
According to this principle,the product of the uncertainty in position $(\Delta x)$ and the uncertainty in momentum $(\Delta p)$ is greater than or equal to $\frac{h}{4\pi}$,expressed as $\Delta x \cdot \Delta p \geq \frac{h}{4\pi}$.

"It is impossible to determine simultaneously the exact position and exact momentum of an electron." This statement is called:
