Question 2

In the position-entanglement experiment, one of the two particles impacts at a particular point on one of the screens. Is the other particle affected by this observation, and if so, how?
 
  A) Yes, the other particle then ceases to feel the force exerted by the first particle.
  B) Yes, the other particle immediately makes a transition into a different quantum state, even though the two particles are some distance apart.
  C) Yes, the other particle transitions into a new quantum state a little later, after the force exerted by the first particle has had time to reach the second particle.
  D) No, the other particle is not affected because they are separate particles.
  E) No, the other particle is not affected because observations such as the impact of a particle cannot in themselves alter other objects in the real physical world.
