A snowflake is still considered water whether its liquid or solid.
The magnitude of the electrical force between a pair of charged particles is 4 Times as much when the particles are moved half as far apart.
This can be easily understood by Columb's law,
![F_{new} = \frac{kQ_{1}Q_{2}}{r^{2}}](https://tex.z-dn.net/?f=F_%7Bnew%7D%20%3D%20%5Cfrac%7BkQ_%7B1%7DQ_%7B2%7D%7D%7Br%5E%7B2%7D%7D)
which state's that the amount of electrical force experienced by two charged particles is inversely proportional to the square of the distance between them.
∴ ![\frac{F_{new} }{F_{old} } = \frac{Distance_{new}^{2} }{Distance_{old}^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BF_%7Bnew%7D%20%7D%7BF_%7Bold%7D%20%7D%20%3D%20%5Cfrac%7BDistance_%7Bnew%7D%5E%7B2%7D%20%20%7D%7BDistance_%7Bold%7D%5E%7B2%7D%20%20%7D)
Now, we know the new distance is half the original distance,
![F_{new} = \frac{kQ_{1}Q_{2}}{\frac{r}{2}^{2} } \\F_{new} = 4\frac{kQ_{1}Q_{2}}{r^{2}}](https://tex.z-dn.net/?f=F_%7Bnew%7D%20%3D%20%5Cfrac%7BkQ_%7B1%7DQ_%7B2%7D%7D%7B%5Cfrac%7Br%7D%7B2%7D%5E%7B2%7D%20%7D%20%5C%5CF_%7Bnew%7D%20%3D%204%5Cfrac%7BkQ_%7B1%7DQ_%7B2%7D%7D%7Br%5E%7B2%7D%7D)
![F_{new} = 4F_{old}](https://tex.z-dn.net/?f=F_%7Bnew%7D%20%3D%204F_%7Bold%7D)
The electrical force of attraction or electrostatic force of attraction between two charged particles refers to the amount of attractive or repulsive force that exists between the two charges. This can be calculated by Columb's Law.
A charged particle in physics is a particle that has an electric charge. It might be an ion, such as a molecule or atom having an excess or shortage of electrons in comparison to protons. The same charge is thought to be shared by an electron, a proton, or another primary particle.

Explanation:
Check out the picture I drew for a minute before reading this...
B. Distance [the red line] is a scalar quantity reflecting how far an object has traveled. Displacement [the green line] is a vector quantity reflecting how far an object has moved from a point. The key difference is that distance can be any sort of path while displacement is always a vector (or a straight line) between a starting point and a finishing point. Sometimes distance and displacement are equal to one another. Sometimes you have a distance traveled, but zero displacement overall; which is what's going on in your question.
A. The distance that the racecar traveled is indeed 500m. But at the end of the lap, it is right back where it started. So overall, it has been displaced 0m.
