If the accuracy in measuring the velocity of a particle increases,the accuracy in measuring its position 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. The more accurately we know the velocity of a particle, the less accurately we can know its position. Therefore, if the accuracy in measuring the velocity increases, the accuracy in measuring its position will decrease.
