Answer :
The pair of protons with velocity 1000 km/s will get closer together before they repel each other.
To find the correct statement, we need to know about the motion of protons.
What's proton?
- Proton is a possibility charged subatomic particle.
- It resides within the nucleus.
What's happened when a pair of protons moves towards each other?
- As a pair of protons are similarly charged, so they will be repelled when they are approach very close.
- Also, the closeness of approaching depends directly on the kinetic energy of these protons.
- So, more the velocity of the protons leads to more kinetic energy and more the closeness between them.
Thus, we can conclude that the pair of protons with velocity 1000 km/s will get closer together before they repel each other.
