According to quantum physics,measuring the velocity of a tiny particle with an electromagnet
A)affects the velocity of the particle.
B)has no effect on the velocity of the particle.

Question

Quizplus · Accepted Answer

According to the Heisenberg Uncertainty Principle, measuring the velocity of a particle with a high degree of accuracy will necessarily disturb its momentum. This means that the more precisely we measure the velocity of a particle, the less accurately we can know its momentum, and vice versa. Therefore, measuring the velocity of a tiny particle with an electromagnet will inevitably affect its velocity.
