A) \[\Delta x\ge \frac{\Delta p\times h}{4\pi }\]
B) \[\Delta x\times \Delta p\ge \frac{h}{4\pi }\]
C) \[\Delta x\times \Delta p\ge \frac{h}{\pi }\]
D) \[\Delta p\ge \frac{\pi h}{\Delta x}\]
Correct Answer: B
Solution :
According to Heisenberg uncertainty principle, the product of uncertainty in momentum \[(\Delta p)\] and in position \[(\Delta x)\] remains constant. \[\Delta x\times \Delta p\ge \frac{h}{4\pi }\]
