Question

If the accuracy in measuring the position of a particle increases, what happens to the accuracy in measuring its velocity? - The accuracy in measuring its velocity becomes uncertain.
- The accuracy in measuring its velocity remains the same.
- The accuracy in measuring its velocity also increases.
- The accuracy in measuring its velocity decreases.

Answer 1

Answer:

- The accuracy in measuring its velocity decreases.

Explanation:

This can be explained by Heisenberg's uncertainty principle which states that the position and velocity of a particle can be determined together exactly in reality.

This principle, unlike Newtonian mechanics deal with particles at microscopic level like that of an electron where if the accuracy in measurement of particle's position increases there will be  decreased accuracy in measurement of velocity of that particle.

There will be an uncertainty in accuracy in the measurement of particle's position and its velocity.
