If the accuracy in measuring the position of a particle increases,the accuracy in measuring its velocity will
A) increase.
B) decrease.
C) remain the same.
D) It is impossible to say since the two measurements are independent and do not affect each other.

Question

Quizplus · Accepted Answer

According to the Heisenberg uncertainty principle, there is a trade-off between the accuracy in measuring the position and velocity of a particle. This means that if the position is measured with high accuracy, the velocity measurement will become less accurate. Therefore, as the accuracy in measuring the position of a particle increases, the accuracy in measuring its velocity will decrease.
